To raise money, a school is selling ice-pops for $1.50. It costs 90 cents to make each pop, and the money from the pops will be used to buy pencils, which cost $1.80 each. How many pops must be sold to buy 100 pencils?
To buy 100 pencils the school needs 100 * $1.80 = $<T>multiply(100, 1.8)=180.0.
Each ice pop sells for $1.50 but costs $.90 to make, for a net profit of $1.50 - $.90 = $<T>subtract(1.5, 0.9)=0.6.
So in order to raise $180.00, the school will need to sell $180.00 / $.60 per ice-pop = <T>divide(180, 0.6)=300.0 ice-pops.
