Question

9) By paying $50 cash up front and thebalance at $35 a week, how long will ittake to pay for a computer costing $960?

Answer 1

We know that we pay $50 up front for a computer costing $960, and that each week we pay $35. We want to know how many weeks will it take us to pay for the computer.

As we paid $50 at the start, at week zero we are

`960-50=910\text{ dollars away from paying the computer}`

Now, as we pay $35 each week, we divide the above value by $35, for knowing the number of weeks needed to pay:

`(910)/(35)=26`

This means, that it will take 26 weeks to pay for the computer, or also 6 months and 2 weeks.
