Tamas is saving $17.00 each week to buy a new sewing machine that cost $175.50. How much weeks will he have to save to have enough money to buy the sewing machine

?

It will take Tamas 11 weeks.

You divide the total = $175.50

By how much money they get per week = $17.00

When you divide those, you get 10.32.

A week has to be a full number. The number 10.32 has a decimal so you move your number to 11 weeks.

The reason why it's not 10 weeks, (when rounding) is because they won't have enough money at 10 weeks but at 11 weeks, Tamas will enough and some extra money.

She has to save 11 weeks
