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?

I was hoping someone could help me do this in the distributive property. I'm a bit confused about how to do it with the distributive property however I know how to do it without.

Answer:

$2.69

Step-by-step explanation:

The original prices of the books are $2.50, $4.95, and $6.00.

You want to buy three books that are on sale at 20% off (or 0.2 as decimal).

In total, you'll save:

[tex]0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6[/tex]

Uce distributive property:

[tex]0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6\\ \\=0.2\cdot (\$2.50+\$4.95+\$6.00)\\ \\=0.2\cdot \$13.45\\ \\=\$2.69[/tex]
