solve or finding unit rate!

Answer 1

Explanation:

We set up a proportion to find X, which in this case is the cost of seven packages.

Proportion: 5.90:2=x:7

Unit cost: 5.90/2=2.95

But we want to find the cost of seven cookies.

So, we multiply the unit cost by 7.

2.95*7= 20.65

Thus, seven packages of cookies costs $20.65.

Answer 2

Answer: 20.65

Explanation:

2.95 is the unit rate x 7 equals 20.65
