Question

pedro open his account with $710 and withdraw $35 per week. maria opened her account with $570 and withdrew $25 weekly .In how many weeks will their accounts be equal

Answer 1

In 14 weeks, if you turn both of those into equations you'll get


`y = - 35x + 710`
and

`y = - 25x + 570`

You should be then able to graph this and see that intersects at 14 weeks at 220 dollars
