Answer:

#7p#

Explanation:

Let the number of people be #p#

The amount received from the people buying ONE of each item is written as:

Money received = #1.5xxp + 3xxp +2.5xxp#

=#1.5p +3p + 2.5p = 7p#

Or you can work it out according to the money that each one of the people spent.

Cost of one lemonade, one bag and one hot dog
= #1.5+3+2.5 = 7#

Money received from #p# people = #7xxp = 7p#

Although the two answers are the same, each method uses a different way of thinking.
