Question

Mario is planning a charity dinner. Each table costs $50 and each chair costs $7 to rent. The other costs of the dinner are $475. Let trepresent the number of tables and let c represent the number of chairs. Which of the following expressions represents the total cost of the dinner?

A. t + c + 475

B. 50t + 7c = 475

C. 7t + 50c + 475

D. 50t + 7c + 475

Answer 1

the answer should be d. the number of tables and chairs he’ll rent is undetermined so you’d need the variables to hold that place and then add the flat rate of 475$. hope that made at least a bit of sense :)
