Question

How do you solve this ???

Answer 1

A pretzel and a drink cost the same: $2.50

Explanation:

`3p+4d=17.50`

`p=d`

Then:

`3(d)+4d=17.50`

`3d+4d=17.50\\7d=17.50`

`d=17.50/7`

`d=2.50`

`p=d=2.50`

Hope this helps.

Answer 2

2.50

There is a total of 7 items that cost 17.50

17.50 divided by 7 is 2.50
