Answer:

$546.25 is the total pay for that week

Step-by-step explanation:

Allen makes $11.50 per hour. That means that if he works 40 hours per week, he will make 460$.

<em>$11.50 * 40 hours = $460 per week</em>

<u>Overtime is any number of hours he works over 40 hours per week</u>. Allen makes 50% more for every hour of overtime. Instead of making 11.50, he will be making $17.25.

<em>$11.50 * 1.5 = $17.25 per hour of overtime</em>

<em>--------------------------------------------------------------------------------------------------------------</em>

To solve the problem:

1. How many hours were worked total on that particular week?

2. How many hours were normal time, how many were overtime?

3. Multiply normal time hours by $11.50, overtime hours by $17.25.

4. Add them together for the total compensation

Solution:

The week of 5/17, Allen worked 45 hours total. This is 40 hours of normal time, 5 hours of overtime.

40 hours * $11.50 = $460.00

5 OT hours * $17.25 = $86.25

$460.00 + $86.25 = $546.25 is the total amount earned that week.

A loan of $900 will be repaid in 36 installment payments of $30.22 each. What the finance charge for the loan?
zimovet [89]
First you need to multiply 36 *$30.22=$1087.92
This gives you the total amount paid

Then subtract 1087.92-900=187.92
This gives you the amount of money you paid in finance charges.

A family of right triangles has side lengths in the approximate ratio 3:4:5. One right angle
velikii [3]

Answer:

2,016.67 sq. cm

Step-by-step explanation:

Given the approximate ratio of the sides of a rectangle as 3:4:5.

Total ratio = 3+4+5 = 12

Area of the rectangle = 1/2*base *height

get the base;

base = 3/12 * 220

Base =  55cm

Get the height

Height = 4/12 * 220

Height = 880/12

Height = 73.3cm

Area = 1/2 * 55 * 73.3

Area = 2,016.67 sq. cm
