Answer:

The answer to your question is below

Step-by-step explanation:

Data

3 shirts and 2 pair of pants

cost =  $300

x = shirt price

y = pants price

a)      3x + 2y = 300

b)      2y = - 3x + 300

        y = -3/2 x + 300/2

        y = -3/2 x + 150

c)      y = -3/2 (20) + 150

        y = -30 + 150

        y = 120  each of the pants costs $120

d)      3x + 2y = 300

 if y = 0

       3x = 300

       x = 300/3

       x = 100              It could be the highest cost of a shirt

e)      3x + 2y = 300

if x = 0

      3(0) + 2y = 300

      2y = 300

      y = 300/2

      y = 150              it could be the highest cost of a pair of pants.
