Answer 2

A.
`20+3x=80`

Explanation:

We are given that Sam is baking cakes at her parent;s bakery.

We have to write an equation to show how many cakes baked by Sam this week.

Let x be the number of cakes baked by Sam this week

If she gets paid for every cakes =$3

Then, she gets paid for x cakes=3x

According to question

Total money made by Sam on this week =20+3x
