Question

You receive X dollars an hour for babysitting. You babysit three hours on Friday and five hours on Saturday. You received $40 for the two days write and solve an equation to find how much you earn per hour

Answer 1

Equation: 3x + 5x = 40

Earned Per Hour: x = 5

Explanation:

Since it's an equation, there has to be an equal sign. The total is 40 and the variable is x. You babysit on Friday and Saturday. On Friday, 3 hrs, and on Saturday, 5 hrs. Your paycheck is x. So far the equation is:

3x + 5x = 40

This is saying that for 3 hours on Friday, you got x money per hour plus the 5 hours on Saturday. Which equals 40 dollars total. Now that we know the equation, we can solve.

First we have to combine like terms. So that's 3x plus 5x which is 8x:

8x = 40

To find x, you divide 40 by 8 to get 5.

x = 5
