Answer:
50+(7d*13)+80+(9d*27)
Step-by-step explanation:
So, there are 13 food booths and each food booth is $50 plus $7 per day.
There are 27 game booths and each game booth is $80 plus $9 per day.
Lets make a short equation for each of the booths.
50+(7d*13)
80+(9d*27)
Lets combine both of the sentences.
50+(7d*13)+80+(9d*27)
So, my expression would be 50+(7d*13)+80+(9d*27).
This is true because 2/5 = 4/10
If u gave 1/10 of a pizza to 6 friends then you would have given them 6/10 of your pizza and have 4/10 left over because 4/10 + 6/10 = 10/10 or 1
Hope this helped :)
