Answer:
Non-proportional; the rate of change is $40/hour
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u>and the line passes through the origin</u>
Let
x -----> the number of hours
y ----> The total charge in dollars
The equation of the line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have

substitute

This relationship is not proportional, because the line not passes through the origin
therefore
Non-proportional; the rate of change is $40/hour
9 goes into 67, 7 times, with a remainder of 4. So we would get
Answer:

Step-by-step explanation:
x = 10
x = 20 / 2
x = 4*5 / 2
Answer: well next time gahni better count right and potentially yes it could effect it
Step-by-step explanation:
Answer:
Amount =$48003.20
Here apply the compound interest formula;
where;
P=Principal amount invested = $37500
r=rate of interest as a decimal, 2.5% =0.025
n=number of compounding per year=1
t=time period the amount in invested=10
In our case, the amount after investing will be;
Interest earned after the period= $48003.20-$37500 =$10503.20
