there are 35 adults and 15 children on the tour. How much money will the group save by visiting the Main deck of the Observation Tower instead of the Top Deck?

Question

Observation tower :Main Deak (adult)        $29

Observation Tower: Main Deal (child).      $19

Answer 1

What are the prices for the adult and child to visit the top top deck?

Based on the problem statement, they are higher.

Let these prices be A and C respectively.

 

The difference in price is then:

 

35*A + 15C - (29*35 + 15*19) = 

 

35*A + 15*C - 1300 <--- use this formula

 

So now plug in the prices, A and C, for the adult

and child visiting the top tower into the formula

in bold to find your answer.

 

For example, suppose the prices are $40 for adult and $25 for children.

35*40 + 15*25 - 1300 = $475
