Answer:
$840
Step-by-step explanation:
Callies family spends an average of $70 per month electric. At that rate what can that family expect to pay electric for 1 year
Note that:
1 year = 12 months.
Hence, if:
1 month = $70
12 months = $x
Cross Multiply
$x = 12 × $70
$x = $840
Therefore, the amount that family can expect to pay in 1 year(12 month) for electric = $840
