There are 5,280 feet in a mile. so 52,800 feet is 10 miles.
We are given
P = $754.43
r = 13.6% annual
for a.
A = 150
for b.
A = 300
First, change the interest into effective monthly
i = (1 + 0.136/12)^12 - 1
Solve for i
Next, use the general formula
A = P i ( 1 + i)^n / (1 + 1)^n - 1
Subsitute P, i, and A for a and b.
Then, solve for n for a and b.
Answer:
he needs 24 cans
Step-by-step explanation:
162.4 - 28 = 134.4
134.4 divided by 56 = 2.4
2.4 * 10 = 24
Steps:
