Question

Calculates the total amount E, in dollars, that she earns for working h hours using the equation E = 10h

Answer 1

So your equation is E=10h.

We know E is equal to 1 so let's plug that is.

1=10h

Now we just solve it.

1=10h    Divide each side by 10

.1=h

Boom!

She has to work .1 hours or 1/10 of an hour to earn 1 dollar.

Hope I helped!
