Question

McKenzie bought 1.2 poi d's of coffee for $11.82. what was the cost per pound? help!!

Answer 1

When they say 'cost PER pound', the 'per' word means you've to divide cost by pound:

$\frac{cost}{pound} = \frac{11.82}{1.2}$

Doing that division on the calculator will give us $9.85, which is the cost per pound of of coffee!

Answer 2

11.82×(1−0.2)=9.456
