Question

A school band performed a concert on four different days. The band soldtickets and snacks each day of the concert for a fundraiser. The first tableshows the numbers of tickets sold and the amounts of money collected fromticket sales. The second table shows the numbers of snacks sold and theamounts of money collected from snack sales.

Answer 1

Part A:

To determine the price per snack, just multiply any value of the column Amount collected, by its corresponding value in the column of Number of snakcs sold:

53.75/43 = 1.25

Hence, the price per snack is 1.25 dollars

Part B:

The equation is a linear equation. The general formula for a linear equation is:

y - yo = m(x - xo)

where m is the slope and (xo,yo) is a pair of values of the table.

m is calculate as follow:

m = (y2 - y1)/(x2 - x1)

m =
