Question

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

(she earns 10 dollars per hour)
at that rate, how many hours does it take her to earn 1 dollar ???

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!
