To babysit one child, Fernando charges $10 to drive to the appointment plus $4 per hour. He saves 30% of the total amount he earns. Brenna charges $6 per hour and saves 25% of the total amount she earns. Which equation can be used to determine the number of hours, h, after which Fernando and Brenna will have saved the same amount of money?

Question

10 + 0.3(4h) = 0.25(6h)
0.3(10) + 4h = 0.25(6h)
0.3(10 + 4h) = 0.25(6h)
0.3(14h) = 0.25(6h)

Answer 1

The correct equation is:

0.3(10 + 4h) = 0.25(6h)

Answer 2

Nosaira solved an equation. Her work is shown below:

3(2x + 1 ) = 2(x + 1) + 1
6x + 3 = 2x + 2 + 1
6x + 3 = 2x + 3
4x = 0
x = 0
She determines the equation has no solution.

Which best describes Nosaira’s work and answer?

Her work is correct, but there is one solution rather than no solution.
Her work is correct and her interpretation of the answer is correct.
Her work is incorrect. She distributed incorrectly.
Her work is incorrect. She moved terms across the equals sign incorrectly.

Answer 3

This is why no one likes you YOUR NOBODY

btw the answer is Her work is correct, but there is one solution rather than no solution.
