Answer:
C 47,745
Step-by-step explanation:
Using the compound interest method to calculate the value.
Inflation rate becomes the interest rate:
Compound interest formular = FV = PV × (1+r)n
FV = future value
PV , present value current amount the family is earning: $45,000
R = interest rate :which is inflation rate
N = number of years : 3
FV = 45,000(1+2/100)3
=45,000(1+0.02)3
=45,000(1.02)3
=45,000x 1.061
=47,745
