Question

Beth swam laps to raise money for a charity. Beth raised $15 plus $0.65 per lap that she swam. She raised a total of $80.

Let x represent the number of laps Beth swam.

What expression completes the equation to determine the total number of laps Beth swam?

How many laps did Beth swim?

Answer 1

The expression you would use is 15 + .65x = 80. If you solve for x, Beth swam 100 laps.

Hope its correct and good luck :)
