Answer:
The balance after 15 year is $831.25 .
Step-by-step explanation:
Formula
Where P is the principle and r is the rate of interest in the decimal form and t is the time.
As given
Caiden earned $475 from mowing lawns last summer.
He deposited this money in an account that pays an interest rate of 3.8% compounded annually.
Here
P = $475
3.8% is written in the decimal form.
= 0.038
r = 0.038
t = 15 years
Put in the formula
Amount = $831.25
Therefore the balance after 15 year is $831.25 .

Step-by-step explanation:
Problem 4:
4a = -15
4b = -75
4c = 125
Problem 5:
5a = -5
5b = 95
5c = -19 
Step-by-step explanation:
<em> See attached for my work. </em>
For problem 4, we substitute the different values given for x and solve.
For problem 5, we set the function equal to the given values and solve.
Answer:
C(x) = 7.5k + 2400 is the expense equation.
Step-by-step explanation:
The fixed cost per month = $2,400
Cost of producing each shoe = $7.5
Here, let k be the number of shoes produced per month .
So, the monthly expense
= Fixed Cost + (Number of shoes produced per month x Cost per shoe)
or, C(x) = $2,400 + ( k x $7.5)
or, C(x) = 7.5k + 2400 is the expense equation.
