E. 14



price per sweater = 300/x

as per the directives:

(300/x - 7.50)(x + 2) = 300

(300 - 7.50x/ x) ( x + 2) = 300

i would like to put values of x from options.

Option C) 10

(300 - 75 / 10)(12) = 300

225/10 * 12 =300

45*6 = 300

270 = 45*6.

don't match.

As 10 gives us 270, we have reduce the value of x a bit.

check out option B .

This is the correct answer.

I plugged in the values here

Start from C, so she bought 300/10, $30 per sweater

30 -7.5 * 12 = 300, Not matching

Try B now
each sweater = 37.5 / sweater

37.5 - 7.5 * 10 = 300
Matches

B
