Answer:
cost = 333 .6 $
Step-by-step explanation:
perimeter = 2 * pi * R = 2 * pi * 15 = 94.24 feet
cost = 3.54 * 94.24 = 333 .6 $
by 10 years it'll be 24439 but by 11 it'll be 25661 so it's technically 11 years
Thats for questions 3 - 8 that you didn't answer. I'm not quite sure how to answer the last two though.
Answer:
after 4 months $8352.96
AFTER 13 MONTH $7426.507
AFTER 23 MONTH A = 7675.69
Step-by-step explanation:
Given data:
P = $9388.81
Compound interest cab be determined as
A = P( 1+ r/n)^(nt)
after 4 months

A = 9513.58
But he has to pay $1160.62 after 4 month so remaining amount is
P = 9513.58 - 1160.62 = $8352.96
AFTER 13 MONTH, so total time is 9 month

A = 8604.79
But he has to pay $1178.29 after 13 month so remaining amount is
P = 8604.79 - 1178.28 = $7426.507
AFTER 23 MONTH so total time is 10 month

A = 7675.69
