Sam is ordering a custom t-shirt for his brother’s birthday. The t-shirt costs $12.50 and each letter costs an

additional $0.50. If Sam can spend up to $20, how many letters can he have printed on his brother’s shirt?

Which inequality can be used to determine the number of letters he can purchase?

• 12.50 + 0.50x ≤ 20

• 0.50x ≤ 20

• 12.50 + 0.50x ≥ 20

• 20 + 0.50x ≤ 12.50
