Answer 1

$8.50*22=187
187*5=935
$935

Answer 2

Answer:

$ 850

Step-by-step explanation:

Martha and her brother started their own car-washing business.

We need to use front-end estimation to find out about how much their business will earn in 5 weeks.

Amount charged per car = $8.50

Number of cars washed per weekend = 22

Therefore, amount earned per weekend = Amount charged per car ×  Number of cars washed per weekend = 8.50 × 22 = $ 187

Amount earned in 5 weeks = amount earned per weekend × 5 = 187 × 5 =  $  935

Therefore, their business will earn $ 935 in 5 weeks.
