Answer:
$936
Step-by-step explanation:
Simple interest is money you can earn by initially investing some money (a.k.a the principal). In return, a percentage (a.k.a the interest) of the initial money invested is added to the principal, this is what makes your initial investment grow.
The equation for simple interest is:
I = P x r x t
P = Principal, $2600
r = interest rate, 12%
t = time involved, 3 years
Fill in the values:
2600 × 0.12 × 3 = $936.00
655 and a half pounds.
You have to divide 10491 by 16 because there is 16 ounces in a pound.
a = -7/3
4 - (3a + 4) = 7
4 - 3a - 4 = 7
-3a = 7
