Stacy works for an ice cream cart vendor. She receives $21 for taking the cart out for a shift plus a commission of 0.35 for each item she sells. Stacy worked a shift Saturday and earned $80.10. Which equation can be used to solve for x, the number of items Stacy sold?

• 80.10 = 0.35x + 21

• 80.10 = 21x + 0.35

• 80.10 = 0.35 + x + 0.35

• 80.10x = 0.35x +21
