1. A caterer charges a flat fee plus $8.50 per
person. If the total cost for a party of 65 people
was $601.50, how much would they charge for
a party of 150 people?

Answers

Answer:

$1,324

Step-by-step explanation:

$8.50 * 65 = $552.50. $601.50 - $552.50 = $49. So the flat fee would be $49.

$8.50* 150 = $1,275. With the flat fee it would be $1,275+$49 = $1,324.

Jess is having a private party at the bowling alley. The party costs $99 plus %3 per person who attends.

Answers

Answer:

Total cost= 99 + 2.97x

Step-by-step explanation:

Giving the following information:

Fixed cost= $99

Variable cost= 3% per person

First, we need to calculate the 3% of 99:

Unitary variable cost= 99*0.03= $2.97

Now, we establish the total cost structure:

Total cost= 99 + 2.97x

x= number of people in attendance

Finally, suppose 200 people attend the party:

Total cost= 99 + 2.97*200

Total cost= $693

The price of a cup of coffee was $2.10 yesterday. Today, the price rose to $2.45. Find the percentage increase. Round your answer to the nearest tenth of a
percent.

Answers

Answer:

16.6667% increase

Step-by-step explanation:

Percentage Increase=Final Value−Starting Value|Starting Value|×100  

Answer:

17%

Step-by-step explanation:

The increase is calculated as the difference between yesterday's price and today's price, hence $2.45 - $2.10 = $0.35

As a fraction of yesterday's price, the fraction is [tex]\frac{0.35}{2.10}[/tex], which reduces to [tex]\frac{1}{6}[/tex].  Expressed as a decimal fraction, this is 0.16...  Shift the decimal point two places to the right to get the percentage increase of 16.6...%.

Since it said to round to the nearest tenth, rounding it makes the answer of 17.0% or 17% because since 6 is bigger than 10, we needed to round up and thus the answer is 17%.

Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student.In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change his grade to an A.A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Question 1Part AWhat inference can be made about Bob Heft in A Flag with 50 Stars?He has important connections to government officials. He works hard and does not give up easily.He is accustomed to success and does not take criticism well.He is more knowledgeable about American history than most students.Question 2Part BWhich evidence from the text best supports the answer in Part A?Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right.He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus.Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag.His teacher replied that if his design was accepted as the new flag, he would be more than happy to change the grade to an A.
