Problem 24 simply equation on how you got the answers

Answer 1

Elaine earns about $17.80 per hour on her work. We need to find how many hours does she need to work in a week to have a salary amounting to $675.00.

We let x be the number of hours Elaine needs to work to have total earnings of $675.00 in a week. Hence, we can write an algebraic equation relating the earning of Elaine per hour and the number of hours she is required to work to get $675.00 as

`17.80x=675.00`

Solve for the value of x by dividing both sides by 17.80. We get

`\begin{gathered} (17.80x)/(17.80)=(675.00)/(17.80) \\ x=37.92\approx38 \end{gathered}`

Elaine needs to work approximately 38 hours in a week to get a total of earnings of $675.00.

Answer: 38 hours
