Answer 1

Answer:

  $75

Step-by-step explanation:

Put the number where the variable is and do the arithmetic:

  A = 52 +23 = 75

Debra earns $75 in a week that she sells 23 books.

Answer 2

Answer:

$75.00

Step-by-step explanation:

We want to find how much she earns, a, when she sells 23 books, b

To find this, we can substitute 23 in for b

a=52+b

a=52+23

Add

a=75

So, if she sells 23 books, she will earn $75.00
