Pet Toys Are the Best charges a $50 membership fee and $5 for each toy. Pet Stuff charges a $30 membership fee and 7.5 for each toy.

Write an inequality statement representing when purchasing toys from Pet Stuff will cost the same or less compared to purchasing from Pet Toys Are the Best.

• 50 + 5x ≥ 30 + 7.5x

• 50 - 5x ≤ 30 - 7.5x

• 50 + 5x ≤ 30 + 7.5x

• 50 + 5x = 30 + 7.5x
