Question

Ariel is saving money for a new computer that costs $650. She has $150, which she puts into an account. Then she adds $25 each week. How many weeks will it take before she can buy the computer

Answer 1

It would take about 20 weeks

Answer 2

25x + 150 = 650
25x = 650 - 150
25x = 500
x = 500/25
x = 20....it would take 20 weeks <==
