Question

Zach wants to buy a skateboard that costs $85. He currently has $15 saved. Zach plans to save d, dollars to have enough to buy the skateboard. Which equation represents the amount of money Zach still needs to buy the skateboard? *

Answer 1

85 = 15 + d

d = 70

Explanation:

Cost of a skateboard = $85

Zach savings = $15

Amount needed more to save = $d

Which equation represents the amount of money Zach still needs to buy the skateboard?

Total cost = available savings + more savings

85 = 15 + d

85 - 15 = d

70 = d

d = 70
