Answer:
The total increase over the 2 years=£1,300.43
Step-by-step explanation:
a). Express the total amount after the first year as shown;
A=P(1+r)^n
A=total amount earned in a year
P=initial amount invested
r=annual interest rate
n=number of years
In our case;
P=£14000
r=5.9%=5.9/100=0.059
n=1
A=14,000(1+0.059)^1
A=14,000(1.059)
A=£14,826
The total amount in the second year
A=14,826(1+0.032)^1
A=£15,300.432
Increase=Amount after 2 years-Initial amount
Increase=(15,300.432-14,000)
Increase=1,300.43
The total increase over the 2 years=£1,300.43
Answer:
the 2nd one
Step-by-step explanation:
Answer:
<h2>28 beads fit on the string.</h2>
Step-by-step explanation:
12 inch = 1 ft.
12 inch can be be written as (5 + 5 + 2) inch.
It is given that, 5 inches require for 12 beads.
Hence, (12 + 12) = 24 beads will take up (5 + 5) = 10 inches.
There are 2 inches more to fill.
5 inches required for 12 beads.
1 inch required for beads.
2 inches will be required for beads.
.
Hence, there will 24 + 4 = 28 beads in total. (Only 4 is added instead of 4.8 because, the number can not be in fraction and there is no space for 29 beads in total).
