Question

Will is selling T-shirts for $15 and sweatshirts for $20 at the basketball game. Wills club team needs to raise over $200 for the upcoming tournament. Sketch graph that will represent both number of T-shirts and sweatshirts he must sell to reach his goal?

Answer 1

X = 0 4 8 12

Y = 10 7 4 1

Explanation:

Given:

Cost of one T shirt = $15

Cost of one sweater = $ 20

To find :

The graph that will represent both number of T-shirts and sweatshirts = ?

Solution:

Let the number of t-shirts be x

The number of sweaters be y

They want to rise a found of $200

Then the equation to represent this situation is

15x + 20y = 200

By trial and error method

15(12) + 20(1) = 200

15(8) + 20(4) = 200

15(0) + 20(10) = 200

15(4) + 20(7) = 200
