Ray earns $15 an hour for up to 40 hours a week. if he works more than 40 hours a week, he is paid time and a half. that means ray is paid 150% of his hourly wage for every hour he works over 40 hours.
how much additional money does ray earn for every hour he works over 40 hours?

$7.50

Step-by-step explanation:

His normal pay is $15/h

Find the OT pay:

OT pay is 150% of his normal pay. Convert 150% to a decimal by dividing by 100 to find the rate in decimal form.

150%/100 = 1.5

Multiply his normal pay by the rate in decimal form.

$15 X 1.5 = $22.5

His OT pay is $22.5/h.

Additional money

= (OT pay) - (Normal pay)

= $22.5 - $15

= $7.5

We always use two decimal places for money.

$7.5 = $7.50

For every hour he works over 40 hours, he is paid an additional $7.50.
