Answer: a) interest earned is $308.2
b) $1983.2
Step-by-step explanation:
a) Interest is calculated by Principal × Rate × Time
From the question, principal is given as $1675; rate = 4.6% = 4.6/100 = 0.046; Time = 4 years
Slot the values into the formula to get the solution
=1675 × 0.046 × 4
= $308.2
Interest earned is $308.2

= $1675 + $308.2
=$1983.2
