A company pays their employees $20 per hour. Using fractional notation, write a proportion that represents how long an employee must work to make $80. Use x to represent the unknown number of hours.

A. 20/x = 1/80
B. 20/1 = 80/x
C. 1/20 = 80/x
D. 80/1 = 20/x

1 answer

To represent the relationship of hours worked to the amount earned using a proportion, we can set it up using the rate of pay and the total earnings. The employee makes $20 per hour, and we want to find out how many hours (x) it takes to earn $80.

The proportion can be set up as follows:

\[ \frac{20}{1} = \frac{80}{x} \]

Therefore, the correct choice is:

B. \( \frac{20}{1} = \frac{80}{x} \)
