Some students want to order shirts with their school logo. One company charges $9.65 per shirt plus a setup fee of $43. Another company charges $8.40 per shirt plus a $58 fee. Which equation represents the number of shirts when both companies charge the same amount?

y = 9.65 + x

y = 8.40 + x

y = 9.65x + 43

y = 8.40x + 58

y = 9.65x

y = 8.40x

y = 9.65x - 43

y = 8.40x - 58
