Question

13 FUNDRAISER The Cougar Pep Squad wants to sell T-shirts in the bookstore for

the spring dance. The cost in dollars to order T-shirts in their school colors is
represented by the equation C = 2t + 3.
a. Make a table of values that represents this relationship.
b. Rewrite the equation in function notation.
c. Graph the function.
d. Describe the relationship between the number of T-shirts and the cost.

Answer 1

See attached worksheet.

Explanation:

See attached worksheet for the table and graph.

I assume that "functation notation: simply means using x and y:

y = 2x + 3

The relationship between the number of T-shirts and cost is defined by y = 2t + 3, where:

y is the total cost,

x is the number of t-shirts,

the 2 is the cost for 1 t-shirt ($/t-shirt), and

3 is a one=time charge of $3 for each order.

The graph (attached) shows a straight line with a y-intercept of 3, the initial order fee. It is linear since the cost of a t-shirt remains the same egardless of order size.
