D. $75

Step-by-step explanation:

The formula used for Simple Interest is given by,

Simple Interest (S.I.) = (P × R × T) ÷ 100

where, P = Principal = 375

R = Rate = 4

T = Time = 5

Putting all values in above formula,

S.I. = (375 × 4 × 5) ÷ 100

⇒ S.I. = 75

Thus, the interest Karen get is $75, which she will use to buy camera.
