Martin works at bluebell ice cream parlor.He earns $87.50 for every 7 hours of work.Based on this information how much money wou

faust18 [17]

Martin will earn $350 for 28 hours of work.

Step-by-step explanation:

Given,

Amount earned in 7 hours = $87.50

Ratio of time to amount earned = 7:87.50

Let,

x be the amount earned in 28 hours.

Ratio of time to amount earned = 28:x

Using proportion;

Ratio of time to amount earned :: Ratio of time to amount earned

$7:87.50::28:x\\$

Product of mean = Product of extreme

$7*x=87.50*28\\7x=2450$

Dividing both sides by 7

$\frac{7x}{7}=\frac{2450}{7}\\x=350$

Martin will earn $350 for 28 hours of work.
