Question

Shari purchased 87 erasers at the rate of $3 per eraser. She sold 63 of them at the rate of $3.50 per eraser and the remaining at the rate of $3 per eraser. Find her profit or loss percent.

Answer 1

12.1% profit

Explanation:

Given data

total eraser= 87

cost =$3 each

Total cost of eraser= 87*3= $261

she sold 63 at $3.5

1. sales made for the 63= $220.5

2 sale made for the remaining= 87-63=24

24*3=$72

Total sales made = 220.5+72=$292.5

her profit= sales-cost

profit= 292.5-261=$31.5

therefore the percent profit is

=31.5/261*100

=0.12*100

=12.1%
