Questions: Heather works mowing lawns and babysitting. She earns 8.60 an hour for mowing and 7.20 an hour for babysitting. How much will she earn for 4 hours of mowing and 1 hour of babysitting?

Solution Steps

Heather earns \$8.60 per hour for mowing. For 4 hours of mowing, her earnings are calculated as follows:

\[ \text{Earnings from mowing} = 4 \times 8.60 = 34.40 \]

Heather earns \$7.20 per hour for babysitting. For 1 hour of babysitting, her earnings are:

\[ \text{Earnings from babysitting} = 1 \times 7.20 = 7.20 \]

To find the total earnings, we add the earnings from mowing and babysitting:

\[ \text{Total earnings} = 34.40 + 7.20 = 41.60 \]
