Given that 15 food booths were rented out for ‘d’ days at $100 plus $5 per day. On the food booths only, the company will earn 15($100+$5d) = $1500 + $75d Given that 20 game booths were rented out for ‘d’ days at $50 plus $7 per day. On the game booths only, the company will earn 20($50 + $7d) = $1000 + $140d
 The total amount that the company is paid is therefore, $1500 + $75d + $1000 + $140d = $2500 + $215d

Answer:

3,200 + 303d

Step-by-step explanation:

Step 1:  

(Add expressions for the total amount for each type of booth. )

16(75 + 8d) + 25(80 + 7d)  

(Use the Distributive Property to expand each expression. )

= 16(75) + 16(8d) + 25(80) + 25(7d)

Step 2:  

= 1,200 + 2,000 + 128d + 175d

(Use the Commutative Property. )

Step 3:  

= 3,200 + 303d

(Combine like terms.)
