Student council is ordering school shirts.

Company A charges $9.65 per shirt plus a setup fee of $43.

Company B charges $8.40 per shirt plus a $58 fee.

Write a system of equations that represents the cost of each company for purchasing x number of shirts.

• A = 9.65 + 43x

  B = 8.40 + 58x

• A = 9.65x + 43

  B = 8.40x + 58

• y =9.65x
  y = 8.40x
