Trey sold t-shirts and hats at a festival. His total profit was $106. He made a $4 profit for each t-shirt he sold. He also made a profit of $34 from selling hats. How many t-shirts did he sell?

18 t-shirts.

Step-by-step explanation:

Trey made a total profit $106 by selling t-shirts and hats. $34 of that profit was from selling hats, subtract 34 from 106 and you will get 72. So he made a profit of $72 in selling t-shirts. The t-shirts were $4 each, so if you divide 72 by 4 you will get 18. Meaning he sold 18 shirts.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

the number 100 represents the number of trials in the experiment.
