Question

Bruce has $150 and saves $20 each week. Katie has $200 and saves $10 each week. after how many weeks will they have the same amount of money? how much money will they have at the time?

Answer 1

so to solve this problem just add bruce's saved money ($150) to the $20 he saves each week. do the same with katie.
bruce katie
week 1 150+20=170 week 1 200+10=210
week 2 170+20=190
week 3 190+20=210 so in 3 weeks bruce will have the same number of money as katie in week 1
