Question

You want to buy three books that are on sale at 20% off. The original prices of the books are $2.50, $4.95, and $6.00. How much will you save? Calculation With Distribution (Show all steps.) Calculation Without Distribution (Show all steps.)

Answer 1

20% off means they will be 80% of their original price. Obviously, we can answer the question as a percentage without even thinking. We will save 20% of the ultimate price.

The first step is to find the cost of everything at 80%.
2.00, 3.96, and 4.80
That adds up to 10.76
The original cost would have been 13.45, so you saved 2.69
