Answer:
The amount he needs to pay = $ 650
Step-by-step explanation:
Area= h* (a+b/2)
= 10 * (10+16/2)
= 10 * (26/2)
= 10 * 13 = 130 sq.feet
The amount he needs to pay = 130 * 5 = $ 650

A=future amount
P=present amount
r=rate in decimal form
n=number of times per year to be compounded
t=time in years
so
P=200
r=0.06
n=1
t=6
evaluate to find A


A=283.704
round
A=$283.70
