The student council at Sparrowtown High School is making T-shirts to sell for a fundraiser, at a price of $12 apiece. The costs,
meanwhile, are $10 per shirt, plus a setup fee of $72. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold? What will the costs be? (Algebra 2)
Answer: 36 shirts and costs $432 step by step: first make an equation with the amount of sold shirts being equal to cost of making them - 12x=10x+72 where x is the number of shirts then, subtract 10x from 12x to get the variable on the same side - 2x=72 finally, divide by 2 to isolate x x=36 shirts to figure out the cost, substitute 36 for x in 10x+72 10(36)+72= 360+72= $432
