Question

The pie store is having a 10% off sale on all of its pies. If the pie you want regularly costs $18, how much would you save with the discount?

Answer 1

If there is 10% of $18 = 18 x 0.9 (1 - 0.1) = $16.20
Therefore the pie costs $16.20
He is saving 18 - 16.20 = $1.80

Answer 2

the answer would be $16.20 divided by 18.00 which would = $1.80
