You are selling lemonade for $1.50 a bag of kettle corn for $3 and a hotdog for $2.50 at the fair right and simplify and expression for the amount of money receive when p people buy one of each item

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.
