Question

Jasons part time job pays him $155 a week.

Answer 1

let 'x' represent the number of weeks that Jason needs to work to save

375 + 155x >= 900

x >= 3.4

if Jason works 3 weeks he will have saves: 375 + 3*155 = $840 which is not enough

thus Jason needs to work at least 4 weeks (by working 4 weeks he will save: 375 + 4*155 = $995).
