Answer

Answer:

b. 1,740

Explanation:

Step1: Calculate average return - rate

First, find the total number of laptops sold and returned over the six - month period. Total sold = $1621 + 1752+1848 + 1634+1725+1780=10360$ Total returned = $223 + 415+421+560+330+304 = 2253$ Average return - rate $r=\frac{2253}{10360}\approx0.2175$

Step2: Estimate number of laptops sold in April

Let $x$ be the number of laptops sold in April. We know the number of returned laptops in April is 379. Since $r=\frac{\text{Number of returned}}{\text{Number of sold}}$, then $x=\frac{379}{0.2175}\approx1742.52\approx1740$ (rounded to the nearest whole number)
