$127.05.

Further explanation

Given:

Jenny charges $9.15 an hour to babysit toddlers and $7.45 an hour to babysit school-aged children. Jenny babysit toddlers for 9 hours and school-aged children for 6 hours

Question:

How much money did she earn in all?

The Process:

Let's prepare the total earnings for each activity.

Total earnings to babysit toddlers

$\boxed{ \ 9 \ hours \times \frac{ \$9.15}{1 \ hour} = \boxed{ \ \$82.35 \ } \ }$

We use decimal operations, like this:

9 . 1 5

9 | 81. | .9 | .45 ⇒ 81. + .9 + .45 = $82.35

Total earnings to babysit school-aged children

$\boxed{ \ 6 \ hours \times \frac{ \$7.45}{1 \ hour} = \boxed{ \ \$44.7 \ } \ }$

We use decimal operations, like this:

7 . 4 5

6 | 42. | 2.4 | .3 ⇒ 42. + 2.4 + .3 = $44.7

Hence, the total earnings in all are $\boxed{ \ \$82.35 + \$44.7 = \boxed{ \ \$127.05 \ } \ }$

Let's also consider the following quick steps.

Quick Steps:

Here we directly calculate the sum of the total earnings in all Jenny's activities. Use parentheses for each multiplication operation.

Total earning $\boxed{ \ = \bigg(9 \ hours \times \frac{ \$9.15}{1 \ hour} \bigg) + \bigg(6 \ hours \times \frac{ \$7.45}{1 \ hour} \bigg) \ }$

$\boxed{ \ \$82.35 + \$44.7 = \boxed{ \ \$127.05 \ } \ }$

Thus, the money Jenny earned in all was $ 127.05.
