Answer:
$9450
Step-by-step explanation:
Answer:
A = $9,450.00
A = P + I where
P (principal) = $9,000.00
I (interest) = $450.00
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 9,000.00(1 + 0.05/1)(1)(1)
A = 9,000.00(1 + 0.05)(1)
A = $9,450.00
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of 5% per year compounded 1 times per year over 1 years is $9,450.00.
It's a simple ratio table.
3 years 7 years 10 years
180 cm 368 cm
The difference between 3 and 7 is 4.
The difference between 180 and 368 is 188.
So every 4 years it increases 188 cm. A rate change of 4/188 simplify this fraction to be 1/47 so every 1 year it increases by 47 cm.
So 7 to 10 years is 3 years, so 47 x 3 = 141cm.
