First you set up your equations Company 1–> 9.65x+43 Company 2–> 8.40x+58
Next you set them equal to each other 9.65x+43=8.40x+58 9.65x-8.40x=58-43 1.25x=15/1.25 x=12 When you plug 12 into both equations you’ll get that they both equal 158.8
First, let x = # of shirts and y = total cost in $. Then create an equation with x and y representing each company. The first company is y = 9.65x + 43 and the second company is y = 8.40x + 58. Since we need to find the # of shirts that would result in the equal total cost, we need to find x when y is equal to the other. Thus here is the setup: 9.65x + 43 = 8.40x + 58, and we would get 1.25x = 15, so x = 12.
