Final answer:
The total cost for a safari group tour for five people is $160. When this cost is shared equally among the five people, each person pays $32.
Step-by-step explanation:
The cost of a safari group tour for two people is $100. For each additional person, there is a $20 charge. To determine how much each of the five people would pay if they equally shared the cost of the tour, first calculate the total cost of the tour for five people. Then divide this total cost by the number of people (5) to find out the cost per person.
The cost for five people would be the base cost for two people ($100) plus the additional charge for the other three people. The charge for three additional people is 3 times $20, which equals $60. The total cost for five people would therefore be $100 + $60 = $160.
To find out how much each person pays, divide the total cost by five:
$160 ÷ 5 = $32 per person.
Thus, if five people share the cost of the tour equally, each person pays $32
