Answer 1

Answer:

A. 45 + b = 88, so b = $43

Step-by-step explanation:

We know that he's earned $45 dollars, plus b dollars for babysitting. This gives us the first part of the equation (45 + b). The total amount he earned was $88, so 45 + b = 88.

Then, you can solve it.

45 + b = 88

-45         -45

0 +  b = 43

b = 43

This means he earned $43 babysitting his younger brother.

Hope this helps :)
