Solve the problem.A pet store is offering a sale of $10 off the retail price of any of its pet beds or pet carriers. (i) Complete the table below to help find an expression that describes the sale price (in dollars) if the retail price is r dollars. Show the arithmetic to help you see a pattern.(ii) Evaluate the expression you found in part (i) for What does your result mean in this situation?
A. (i)
(ii) 58 + 10 = 68; This means that if the pet bed or pet carrier was originally retail priced at $58, it would be now cost $68.
B. (i)
(ii) 58 + (-30) = 28; This means that if the pet bed or pet carrier was originally retail priced at $58, it would be on sale for $28.
C. (i)
(ii) 58 + (-10) = 48; This means that if the pet bed or pet carrier was originally retail priced at $58, it would be on sale for $48.
D. (i)
(ii) 58 + (-50) = 8; This means that if the pet bed or pet carrier was originally retail priced at $58, it would be on sale for $8.
