Answer:

  • $10 per hour
  • 0.1 hours

Step-by-step explanation:

To find Carys' earnings in one hour, fill in h=1 in the formula:

  E = 10·1 = 10

Carys earns 10 dollars per hour.

__

To find the number of hours required to earn 1 dollar, fill in E=1 in the formula:

  1 = 10h

  0.1 = h . . . . . divide by 10

It takes 0.1 hours for Carys to earn 1 dollar.

Answer:

  • it takes carys 0.1 hours to earn 10 dollars

Step-by-step explanation:

1. First we want to know how much Carys earns for working 1 hour. Since h gives us the number of hours Carys works, we can substitute h= 1 into the equation and solve for E.

  • E = 10h
  • E = 10 ⋅1
  • E = 10

Carys earns 10 dollars per hour

2. For the second question, we know the total amount Carys earns equals 1  dollar, but we do not know the number of hours. We'll substitute into our original equation again.

  • E = 10h
  • 1 = 10h
  • 1/10 = 10h/10
  • 0.1 = h

It takes Carys 0.1 hours to earn 1 dollar.

  • Carys earns 10 dollars per hour.
  • It takes Carys 0.1 hours to earn 10 dollars.
