Algebra Difficulty 1.4 Junior Find the answer Canada

A store sells jellybeans at a fixed price per gram. The price for
250 g of jellybeans is $7.50. What mass of jellybeans sells for
$1.80?

Pick one

Solution

The store sells 250 g of jellybeans for $7.50, which is 750
cents.

Therefore, 1 g of jellybeans costs $750 \div 250 = 3$ cents.

This means that $1.80, which is 180 cents, will buy $180 \div 3 = 60$ g of jellybeans.
