I just need someone to check my answers, I did all the work but I'm not sure even though I checked my work 3 times but that's not the point. (sorry I talk too much ;-;)

4. Samantha types 40 words per minute. How many words can Samantha type in 8 minutes?

5. How many miles can a car travel on 15 gallons of gas if it travels 28 miles on 1 gallon of gas?

A. 43 miles
B. 270 miles
C. 405 miles
D. 420 miles

My answers:

1. D. 72inches-2 yards
Reason: I kinda guessed on this one

2. D. 423 mph
Reason: 3/1,269, 3 doesn't go into 1 so change that to does 3 go into 12? Yes, 4 times because 4 * 3 is 12 so put the 4 on top of the 2 and times 4 * 3 which again is 12 so 12 - 12 = 0 so then bring the 69 now and 3 goes into 69, 23 times so the answers is 423 I believe.

3. D. Bag A and Bag B are equally good values
Reason: I uh guessed on this one too because I don't have a clue what the answer is

4. C. 320 words
Reason: I timesed 40 by 8, 8 times 0 is 0, 8 times 4 is 32 put the so the answer is 320 I hope

5. D. 420 miles
Reason: 28 times 15, 8 times 5 is 40 so put the 0 under the 5 and put the 4 over the 2, 5 times 2 +4 is 14 so the first number is 140. put a 0 under the first 0 because we don't use that spot anymore, 1 times 8 is 8 and 1 times 2 is 2 so the second number is 280, 280 + 140 = 420. 0 + 0 = 0, 8 + 4 = 12, add the one to the hundered place so 2 + 1 + 1 = 4.

Yani buys a certain brand of cereal that costs $10 per box. Yani changes to a super-saving brand of the same size. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.

y = 7x

Part A: How many more dollars is the price of a box of Yani's original brand of cereal than the price of a box of the super-saving cereal? Show your work.

Part B: How much money does Yani save each month with the change in cereal brand if he buys 5 cereal boxes each month? Show your work.

1. Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to determine the slope and how the equation was determined.
3. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4. Test the residuals of two other points to determine how well the line of best fit models the data.
