Question

A cell phone company recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June's

sales. If y represents July's sales, which equation can be used to determine the sales in July?

0 A y = n - 0,26n

OB y = n - 0.26

0 C. y = n + 0,26n

OD. n = y-0.26

22

Answer 1

Option A. is correct.

Explanation:

Given: A cell phone company recently noticed a
`26\%` sales decrease in the month of July compared to June such that
`n` represent June's sales.

Also,
`y` represents July's sales.

To find: equation that can be used to determine the sales in July

Solution:

June's sales
`=n`

Decrease in sales
`=(26)/(100)n=0.26n`

So,

July's sales
`=n-0.26n`

Also,

July's sales
`=y`

Therefore,

`y=n-0.26n`

So, option A. is correct.
