120%

Step-by-step explanation:

Over the past few years, Michael has increased his fee for mowing lawns from $5.00 per hour to $11.00 per hour. What percent did Micael's fee increase?

The formula for Percentage increase is given as:

Increase/Initial amount × 100

Increase = New amount - Initial amount

From the above question, our increase = $11 - $5 = $6

Therefore,

Percentage increase = $6/$5 × 100

= 120%

Michael's fee increased by 120%
