The student council at Oxford High School is making T-shirts to sell for a fundraiser, at a price of $12 apiece. The costs, meanwhile, are $10 per shirt, plus a setup fee of $130. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold? What will the costs be?

Step-by-step explanation:

First find the profit they will make from each shirt:

= Selling price - Cost price

= 12 - 10

= $2

They need to cover the cost of setting up which is $130. The number of shirts to sell given a profit of $2 from each shirt is:

= 130 / 2

=65 shirts

Cost of selling 65 shirts:

= 65 * 10 per shirt

= $650

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
