Question

Miles has saved $40. He wants to buy a cell phone for $129 in about 4 months. To find out how much he should save each week, he wrote 40 + 16x = 129. Is his equation accurate? Why or Why not?

Answer 1

Answer: No, the equation is not accurate.

Step-by-step explanation: The proper equation is 4x + 40 = 129. This is because 16 is nowhere in the scenario, and the term before x is months, so the correct term would be 4x.
