Answer: Sweatshirts Sold: 3, 5, 8, 9, 12
Money Collected: 60, 100, 160, 180, 240
Explanation:
To find the missing blanks, we first need to find the rate of change between x and y. We can find the rate of change by using the first data values 3(representing x) and 60(representing y).
To find the rate of change, we have to divide the y value by the x value to find how much y is given x value.
60 ÷ 3 = 20
The rate of change is 20 given x values. We can now use this equation to find our missing values:
x = y ÷ 20 <-- This will be used to find a missing x value.
y = 20x <-- This will be used to find a missing y value.
20(5) = 100 <-- solve for y
20(8) = 160 <-- solve for y
180 ÷ 20 = 9 <-- solve for x
20(12) = 240 <-- solve for y
