Answer:
1. $327.60
2. $21,560.00
3. $2,208.28
Step-by-step explanation:
The formula for simple interest is:
I = Prt
where
I = amount of interest
P = principal amount
r = annual interest rate
t = number of years
The total future amount after earning simple interest is the principal polus the interest.
F = P + Prt
F = P(1 + rt)
1.
F = P(1 + rt)
F = $210(1 + 0.08 * 7)
F = $327.60
2.
F = P(1 + rt)
F = $14,000(1 + 0.06 * 9)
F = $21,560.00
3.
F = P(1 + rt)
F = $1,900(1 + 0.059 * 2.75)
F = $2,208.28
4hour.
<h3>Justification:</h3>
<u>We are given time takes to travel is inversely with an average speed</u>.
- When average speed is 40mph, it takes 2hour.
Then,
<u>If average speed is 80mph, let time taken be x</u>:
- 40/2 = 80/x
- 40x = 160
- x = 160/40
- x = 4
<u>Hence, it takes 4 hour to travel to a destination with 80mph</u>.
Answer:
(i) interest = $1680
(ii) total amount = 13680
Step-by-step explanation:
Interest.
12000 × 14/100
=168000/100
=1680
Total amount.
Interest + Loan
1680 + 12000
=13680
