Question

I have a question..??!!!

Write and solve an equation to solve each problem.

Trey went to the batting cages to practice hitting. He rented a helmet for $4 and paid $0.75 for each group of 20 pitches. If he spent a total of $7 at the batting cages, how many groups of pitches did he pay for?

Answer 1

please help me!!!!

Answer 2

4 groups of 20 pitches. you make 7=4 +0.75x and solve for x

Answer 3

so 0.75x + 4 = 7

Answer 4

yep . $4 for the helmet plus 0.75x . x because your trying to figure out the number of groups, but you know how much it costs per "20 pitches" . Your total spending is $7 so that is your =7

Answer 5

is the answer for x 4??
