Answer 2

Answer:

Answer:https: y+3x-8

Step-by-step explanation: first: put your first point at -8

second: then from the point at -8, go up three times, and over to your right one time

now do that however many times you need to

explanation:

- the y-intercept is the initial value which is -8. the line must pass through -8 so you would start your line at -8

- your slope is 3x. slope is so you rise 3 time and over 1 time

y = -x – 4 -4.0

y-intercept = -4/1 = -4.00000

Carleen Bailey works at a boutique eight hours a day, earning $9.48 an hour. She is asked to work two additional hours at time and a half to help prepare for an incoming shipment. How much will she earn for these two hours of overtime?

Answers

Answer:

The correct answer is $23.70.

Step-by-step explanation:

9.48 times 2.5 is 23.7

Final answer:

Carleen Bailey would earn $28.44 for the two hours of overtime she worked. She earns 1.5 times her normal hourly wage for overtime hours.

Explanation:

Carleen Bailey earns $9.48 for each regular hour she works. When she works overtime, she earns 1.5 times her normal rate for each additional hour. That means her overtime rate is $9.48 * 1.5 = $14.22 per hour. Therefore, if she works 2 hours of overtime, she will earn $14.22 * 2 = $28.44 in total for the overtime hours.
