700 - 35 every week

do i put them together

anonymous · Answer

x is the number of weeks

Diego's amount after x weeks: 700-35x

Juan's amount after x weeks: 450 + 15x

These are equal so write equation

700-35x =450 +15x

700-450 = 35x +15x

250 = 50x

x = 5 weeks

450 +15*5 = 450 +75 = $525
