Answer:
Correct answer is (C) $12.75
Step-by-step explanation:
Cost of the tour = $5.25 + cost per person(Number of persons)
Let the additional amount for each person in the vehicle by x.
There are 7 people in Skubic family.
So, cost for them = 5.25 + 7x
The total amount they paid = $22.75.
Then, for Skubic family, the cost equation is:
5.25 + 7x = 22.75.
7x = 22.75 - 5.25
= 17.5
x = 17.5/7
= 2.5
Now, there are 3 people in Shaw family.
So, cost for them = 5.25 + 3x
But, x = 2.5
Hence, total cost for Shaw family = 5.25 + 3(2.5)
= 12.75
Hence, the correct answer is (C) $12.75.
