Question

The members of a basketball team are selling t-shirts during spirit week. The cost is $20 for the design and $1.50 to print each t-shirt. The cost, y, to print x t-shirts is given by the linear equation y = 1.5x + 20.

Answer 1

Explanation:

It is given that,

The cost is $20 for the design and $1.50 to print each t-shirt.

The cost, y, to print x t-shirts is given by the linear equation:

y = 1.5x + 20 ....(1)

Let us assume we need to find the total cost when he print 10 tshirt.

Put x = 10 in equation (1)

y = 1.5(10) + 20

= 15 + 20

= $35

Hence, the net cost is 35 when he had to print 10 tshirts
