Emma pats $108 every six weeks for tennis lessons. What is the price per year for tennis lessons

Answer 1

Cross multiply, solve for $?:

$108 $?

------------ = ------------

6 weeks 52 weeks

This is a ratio problem. One of the simplest ways of solving single variable ratios is framing it in the form above.

If you don't want to visualize it this way, you can also reduce the left side of 108/6 to get the price per week and then multiply by the number of weeks...but its functionally the same thing.
