Question

Doug’s job pays 8.80 per hour and Joanne’s salary is 3/4 Doug’s salary per hour. They need to raise at least 1,500 to repair their car. How many hours must each of them work if they agree to each work the same number of hours?

Answer 1

Answer: The solution to the equation is
`\(x = (7500)/(77)\)`.

Explanation:

Doug's hourly wage is $8.80. Joanne's hourly wage is 3/4 of Doug's, which is $8.80 * 3/4 = $6.60.

They are both working the same number of hours, which we'll call 'x'. So, the total amount of money they earn is the sum of their individual earnings:

Doug's earnings: $8.80 * x

Joanne's earnings: $6.60 * x

Together, they need to earn at least $1500. So, we set up the equation:

$8.80 * x + $6.60 * x = $1500

Solving this equation gives us the number of hours (x) they each need to work. The solution to the equation is
`\(x = (7500)/(77)\)`, which is approximately 97.4 hours.

So, Doug and Joanne each need to work approximately 97.4 hours to raise at least $1500 for the car repair
