Question

Cristiano is saving money to buy a bike that costs $189. He has saved $99 so far. He plans on saving $10 each week. In how many weeks will he have enough money to buy the bike?

Answer 1

9 weeks to go

Explanation:

Your equation:

`(ntimes$10) + $99 = $189`

where n is the number of weeks.

`ntimes$10=$90`

`n=($90)/($10)`

`n=9` weeks.

9 weeks later he can buy a bike.
