A company rents out 15 food booths and 20 game booths at the county fair. The fee for a food booth is $100 plus $5 per day. The fee for a game booth is $50 plus $7 per day. The fair lasts for 'd' days, and all the booths are rented for the entire time. Write and simplify an expression for the amount in dollars the the company is paid.

Respuesta :

105 times 15= 1575
57 times 20= 1140 
1140+1575= 2715 

(2715)(d)= x 

x being the total amount the company paid
- Food booth

From the sentences above, we can see that people need to pay $ 100 as intial payment, and additional $5 for each day they use the booth. Since he company has 15 food booths, the expression would bey

y = 15  (100 + 5d)
in which y = total amount that company received and d is the number of days the booth is rented

- Game Booth

From the sentences above, we can see that people need to pay $ 50 as intial payment, and additional $7 for each day they use the booth. Since he company has 20 game booths, the expression would be

y = 20 (50 + 7d)
in which y = total amount that company received and d is the number of days the booth is rented


- For both game booths and food booths

y    = [15 ( 100 + 5d)  ]      +        [ 20 (50 + 7d)]

y = 1500 + 75d+ 1000 +140d

y = 2500 + 215d
