Answer 1

Let x be the normal cost for an individual.

Given that Keith and his friends purchase the group package which costs $78 for 6 people. and that is $3 less per person. Since there are 6 people, it is $18 less.

The equation that represents this is

6x + 18 = 786x+18=78

6x = 966x=96

x = 16x=16

The normal cost for an individual is $16.
