$226.70

Step-by-step explanation:

Answer 2

Answer : The money he save in one year would be, $177.009

Explanation :

First we have to calculate the cost of 1 incandescent bulbs.

Cost of 1 incandescent bulbs = Cost of single bulb × Cost of annual operating

Cost of 1 incandescent bulbs = $1.47 × $32.86

Cost of 1 incandescent bulbs = $48.3042

Now we have to calculate the cost of 10 incandescent bulbs.

Cost of 1 incandescent bulbs = $48.3042

Cost of 10 incandescent bulbs = 10 × $48.3042

Cost of 10 incandescent bulbs = $483.042

Now we have to calculate the cost of 1 CFL bulbs.

Cost of 1 CFL bulbs = Cost of single bulb × Cost of annual operating

Cost of 1 CFL bulbs = $3.99 × $7.67

Cost of 1 CFL bulbs = $30.6033

Now we have to calculate the cost of 10 CFL bulbs.

Cost of 1 CFL bulbs = $30.6033

Cost of 10 CFL bulbs = 10 × $30.6033

Cost of 10 CFL bulbs = $306.033

Money he save in one year = Cost of 10 incandescent bulbs - Cost of 10 CFL bulbs

Money he save in one year = $483.042 - $306.033

Money he save in one year = $177.009

Thus, the money he save in one year would be, $177.009
