Chapter 1.1, Problem 32PPS

(a)

To determine

To write: the expression that can be used to find the total cost of admission

Answer to Problem 32PPS

The expression will be $\left(4\times 8\right)+\left(3\times 5\right)+4$

Explanation of Solution

Given:

  

Calculation:

Cost of ticket of 1 adult = $\$8$

So, cost of tickets of 4 adults = $\$4\times 8$

Cost of ticket of 1 child = $\$5$

So, cost of tickets of 3 children = $\$3\times 5$

Cost of ticket of 1 senior = $\$4$

Thus, the expression for the total cost of admission in a zoo for 4 adults, 3 children and 1 senior is

  $\left(4\times 8\right)+\left(3\times 5\right)+4$

Conclusion:

Therefore, the expression will be $\left(4\times 8\right)+\left(3\times 5\right)+4$

(b)

To determine

To find: The total cost.

Answer to Problem 32PPS

The total cost of admission in a zoo for 4 adults, 3 children and 1 senior is $51.

Explanation of Solution

Given:

  

Calculation:

Now, evaluate this expression

  $\left(4\times 8\right)+\left(3\times 5\right)+4$

First solve the bracket.

  $\left(4\times 8\right)+\left(3\times 5\right)+4=32+15+4$

Now, perform the addition

  $\left(4\times 8\right)+\left(3\times 5\right)+4=32+15+4=51$

Thus, the total cost of admission in a zoo for 4 adults, 3 children and 1 senior is $\$51$ .

Conclusion:

Therefore, the total cost of admission in a zoo for 4 adults, 3 children and 1 senior is $\$51$ .
