Question

The admission to a local carnival is $8.25 per person and $1.50 for each ride. How much more will it cost a group of 3 friends to ride 8 rides each than to ride 3 rides each?
$7.50
$22.50
$32.25
$48.75

Answer 1

3*(8-3)*(1.50)=22.5 second option

Answer 2

Answer:

$22.50

Step-by-step explanation:

Number of friends = 3

Admission cost per person = $8.25

So, total admission cost for 3 persons =$3 \times 8.25$

                                                                =$24.75$

Each friend takes 8 rides

So, total rides taken by 3 friends = $8 \times 3 =24$

Cost of 1 ride = $1.50

So, Cost of 24 rides =  $24 \times 1.50 =36$

So, total cost for group of 3 friends in which each friend takes 8 rides = 24.75+36 =$ 60.75

If Each friend takes 3 rides

So, total rides taken by 3 friends = $3 \times 3 =9$

Cost of 1 ride = $1.50

So, Cost of 9 rides =  $9 \times 1.50 =13.5$

So, total cost for group of 3 friends in which each friend takes 3 rides = 24.75+13.5 =$ 38.25

Difference in both the costs = $60.75 -$38.25=$22.50

Hence it will cost $22.50 more than a group of 3 friends to ride 8 rides each than to ride 3 rides each.

So, Option B $22.50 is correct.
