Answer:
The value of Mary's investment after two years = £12362.7
Step-by-step explanation:
P = Principal / initial amount
R = rate of interest per cent per year
T = number of years
A = final amount at the end of T years
Then:
A = P*(1 + R/100)^2
In our example:
P = £12000
R = 1.5 per cent per year
T = 2 years
Thus:
A = 12000*(1 + 1.5/100)^2
= 12000*(1 + 0.015)^2
= 12000*(1.015)^2
= 12000*(1.030225)
= 12362.7
Value of investment after two years = £12362.7
1 U.S. CUP - 0.0625 U.S. GALLONS
So? Convert the cups to gallons.
7 DAYS/PER WEEK
1.5 x 7 = 10.5
So... half a cup is about 0.03125 gallons.
0.03125 + (10 x 0.0625) = ???
Drum roll please...
Plot twist: You can do it yourself.
