Question

Jennifer plans to attend the Lawrence County Fair and is trying to decide what would be a better deal. She can pay 38 for unlimited rides, or she can pay12 for admission plus 2 per ride. If Jennifer goes on a certain number of rides, the two options wind up costing her the same amount. What is that cost? How many rides is that? It will cost Jennifer____ for both options if she goes on ____ rides.

Answer 1

Jennifer needs to go on 13 rides for both options to cost the same. At this number of rides, both options will cost her $38.

Step-by-step explanation:

To find out the number of rides for which both options cost the same, we need to set up an equation where the cost of the first option (unlimited rides for $38) equals the cost of the second option (admission plus $2 per ride). Let the number of rides Jennifer plans to go on be represented by 'r'.

Using the given information, the equation will be:

38 = 12 + 2r

We solve for 'r' as follows:

• Subtract 12 from both sides: 38 - 12 = 2r
• This simplifies to: 26 = 2r
• Divide both sides by 2 to find 'r': 13 = r

So, when Jennifer goes on 13 rides, both options will cost her the same, which is $38.

Therefore, It will cost Jennifer $38 for both options if she goes on 13 rides.
