Sam is baking cakes at her parents' bakery. she gets paid $20 a week in addition to $3 for every cake she bakes. she made $80 this week. write an equation to show how many cakes sam baked this week. 20 + 3x = 80 20 − 3x = 80 80 + 3x = 20 80 − 3x = 20

A.

Step-by-step 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

Substitute the values then we get

This is required equation to show how many  cakes baked by Sam this week.

Hence, option A is true.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

the answer will be b x² +x-1
