Question

An electronic store sold 6% of the cell phones that were on sale. If only 21 cell phones were sold,

Answer 1

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of phones that were on sale, given that 6% of the cell phones that were on sale, therefore:

number of cell phones sold = 6% of x = 0.06 × x = 0.06x

21 phones were sold, hence:

0.06x = 21

x = 21/0.06

x = 350 phones

This means that 350 cell phones were on sale.

Number of cell phones not sold = total number of cell phones that were on sale - number of cell phones sold

Number of cell phones not sold = 350 - 21

Number of cell phones not sold = 329
