13 FUNDRAISER The Cougar Pep Squad wants to sell T-shirts in the bookstore for
ANTONII [103]

Answer:

See attached worksheet.

Step-by-step 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.

Effectus [21]
So this is a BIDMAS question so first you do the division and multiplication so you do (15 x 18) + (12/3) + 9 and get 270 + 4 + 9 which you just add to get 283. Hope this helps :)
