Clara goes miniature golfing. She pays $7.50 for an admission ticket and $6.25 for each round she golfs. The total amount Clara pays for admission and the number of rounds she golfs is $26.25. Which equation can be used to determine the number of rounds, x, that Clara golfs?

A - 6.25x + 7.50 = 26.25

B - G.25x - 7.50 = 26.25

C - 7.50x + 6.25 = 26.25

D - 7.50x - 6.25 = 26.25

Answers

Answer:

A.

Step-by-step explanation:

Answer:

6.25x + 7.50 = 26.25

Step-by-step explanation:

Clara played 3 rounds of golf.

The admission fee is = $7.50

Let the number of rounds be = x

Each round costs = $6.25

Total money Clara paid = $26.25

We can denote this in equation form as:

6.25x + 7.50 = 26.25

Now we will solve for x

6.25x = 26.25 - 7.50

=> 6.25x = 18.75

=> x = 3

Hence, Clara played 3 rounds of golf.

Leila is the better runner.

Step-by-step explanation:

Velocity of Leila = (3×3/5)/(7/60) km/h
