In the honey shop, the bulk price of honey is $5 per pound and the minimum spend is $40 before tax. The honey is taxed at $1 per pound. If Penny has paid $240 for honey, by how many pounds has Penny’s purchase exceed the minimum spend?
Including tax, a pound of honey costs 5 + 1 = <T>add(5, 1)=6 dollars
The minimum purchase equals 40 / 5 = <T>divide(40, 5)=8.0 pounds of honey.
Penny has bought 240 / 6 = <T>divide(240, 6)=40.0 pounds of honey
Penny has exceeded the minimum purchase by 40 - 8 = <T>subtract(40, 8)=32 pounds.
