Answer :
Amount of money received when p people buy one of each item is 7 p.
Step-by-step explanation:
Here, the cost of 1 lemonade = $1.5
The cost of 1 kettle of corn = $3
The cost of 1 hot dog = $2.5
So, if 1 person buys one of each item :
Then the total cost = Cost of { 1 lemonade + 1 kettle of corn + 1 hot dog)
= $1.5 + $3 + $2.5 = $7
So, 1 person spend $7 if one item of each type is purchased.
So, the total amount spent by p people buying each item of same type
= p x ( amount spent by 1 person)
= p x ( $ 7) = 7 p
Hence, amount of money received when p people buy one of each item is 7 p.
