Question

Jack needs to save $125 to go to a concert. He has saved $35. He makes $7.50 an hour at his job. Which equation and solution can be used to show how many hours Jack must work in order to have enough money to go to the concert?

A.)125x + 35 = 750; x = 5.75

B.) 35x + 125 = 750; x = 18

C.)35−7.5x=125;x=6

D.)7.5x + 35 = 125; x = 12

Answer 1

Answer: I just took the test and the answer is D.) 7.5+35=125; x = 12

Step-by-step explanation: So Jack already has $35 and he makes $7.50 an hour. So if we do 35(7.5 x X). If we do 7.5x12, that is equal to 90. Now they still have that additional $35 they saved. 90+35=125. Hope this helps :)

Answer 2

The correct answer would be D, 7.5x + 35 =125.

You would subtract 35 from 125 so that you have 7.5x=90. Then you would divide 7.5 from 90 to get your answer of 12.

Hope this helps! :D
