Answer:
3/8
Step-by-step explanation:
The expression can be rewritten as b + 1/8 + c
substitute b and c
2 + 1/8 - 7/4 = 16/8 + 1/8 - 14/8 = 3/8
Answer:

Step-by-step explanation:
The formula for simple interest I is
I = Prt, where
P = the principal (amount invested)
r = the interest rate per period and
n = the number of periods
In this problem, the interest rate is annual, so n = 1.
We must write the interest rate as a decimal fraction.
Let x = amount of each investment. Then
0.02x = interest at 2 %
0.07x = interest at 7 %
0.09x = interest at 9 %
0.18x = total interest
