Answer:
Step-by-step explanation:
6 (3n+5)
use the distributive property
18n+35
This can be solved by using a simple algebraic equation.
For example, in the first column, Caleb worked 5 hours. We do not know how much he makes per hour, so let that be x. He earned a total of $36.25, so the equation can be written as 5x=36.25.
Divide by 5 on both sides, and you get x= 7.25
He earns $7.25 per hour of work.
Repeat this for all the workers:
Jeremy: 7.5x=65.25
x= $8.70
Maria: 4.25x=34.00
x= $8
Rosa: 8x=54.00
x= $6.75
Jeremy has the greatest hourly rate
Well, suppose she gets x points in 7th round. Then she wants mean to be 75, meaning
(72+79+74+76+76+75+x)/7=75
Can you find x from here?
Interest on $600 for 4 months at 9% would be $216 because 600x4x9%=216
