Question

At the beginning of the month, Kimberly had $65.78. since then, she has received three payments of $32.50 from her babysitting job. Kimberly’s 2 sisters each helped her babysit once during the month, so Kimberly paid them each $8.75. If Kimberly did not spend any money, how much money does she have now?

Answer 1

You really need to break the question into individual sentences.
Start with $65.78

Add 3 x $32.50 from the 3 babysitting jobs

Subtract 2 x $8.75 for paying $8.75 to each sister

Summary:

$65.78 + 3($32.50) - 2($8.75) = $145.78

Answer 2

$145.78

Explanation:

Kimberly had a amount = $65.78

She has received three payments of $32.50 = 32.50 × 3

= $97.50

Kimberly's 2 sisters helped her babysit once , so Kimberly paid them each $8.75 = $8.75 × 2

= $17.50

Now she has the amount = 65.78 + 97.50 - 17.50

= 163.28 - 17.50

= $145.78

She have $145.78 now.
