Answer:
3,370 + 220d
Explanation:
Food booth = 15
Game booth = 23
The fair lasts for d days
Cost of a food booth = 125 + 7d
Total cost of food booth = 15(125 + 7d)
= 1875 + 105d
Cost of a game booth = 65 + 5d
Total cost of game booth = 23(65 + 5d)
= 1495 + 115d
Total amount paid to the company = Total cost of food booth + Total cost of game booth
= (1875 + 105d) + (1495 + 115d)
= 1875 + 105d + 1495 + 115d
= 3,370 + 220d
