The percent of decrease is 15%

Further explanation:

We have to calculate the percentage decrease

The formula for percent decrease is:

Percent\ decrease= \frac{decrease}{original\ quantity}*100\\While\ decrease\ is\ calculated\ as:\\Decrease=Original\ quantity-decreased\ quantity

Given

Original Quantity=762 students

Decreased Quantity=645 students

Decrease=762-645

=117

Putting values in the formula

Percent\ Decrease=\frac{117}{762}*100\\=0.15*100\\=15\%

The percent of decrease is 15%

____ [38]

Answer:

$181.44

Step-by-step explanation:

First, you convert the hours worked to minutes <em>(h)×60=(min)</em>.

4 × 60 = 240     4.5 × 60 = 270        7.25 × 60 = 435

Then, you add the minutes worked together.

240 + 270 + 435 = 945

Then, convert the total minutes worked to ours.

945 ÷ 60 = 15.75

Finally, multiply 11.52 (the pay per hour) by 15.75 (the total hours worked)

$11.52 × 15.75h = $181.44
