The skubic family and the shaw family went on a safari tour in which they drove their own vehicles through the park to view the animals. the cost of the tour was $5.25 per vehicle plus an additional amount for each person in the vehicle. the skubic family had 7 people in their vehicle and paid $22.75.

if the shaw family had 3 people in their vehicle, how much did they pay?

$2.50$7.50$12.75$17.25

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.
