Answer:

Catherine has $12.50 to spend on erasers. If each for 50 cents, how much can she buy?

<h3>Answer:</h3>

After 16 downloads the charges will equal each other.

<h3>Step-by-step explanation:</h3>

First set up an equation

x = Downloads

12 + 1x = 5 + 1.5x

Solve

12 + 1x = 5 + 1.5x <- Rewrite your equation

-5          -5            <- Subtract 5 from both sides

 8 + 1x = 1.5x       <- Simplify

      -1x    -1x         <- Subtract 1 from both sides

        8 = 0.5x      <- Simplify

        8 = 1/2x       <- Convert 0.5 to a fraction to make the next step easier

       16 = x            <- Multiply both sides by 2 to divide by

                                 a fraction
