For the cost to be the same for both options, y=y, so we can say:
10.5x=7.5x+30 subtract 7.5x from both sides
3x=30 divide both sides by 3
x=10
So they would have to purchase ten t-shirts from each company for the cost to be the same. And that cost is either equation using 10 for the x value
y=10.5(10)=$105.00
10.5x=7.5x+30 subtract 7.5x from both sides
3x=30 divide both sides by 3
x=10
