Question

Joana is meeting her friend at the Fair and the admission to get in is $10. Each ride/food costs $1.25 each Create an equation for Joana to use so she can calculate how much money she will be spending while she’s at the fair.

Answer 1

y=1.25x+10

Explanation:

you can put this into the formula “y=mx+b”. y is the final amount, x is how many times joana gets food or goes on a ride. You can plug into the equation the two parts we know. We know that no matter what, if she goes into the fair, she is going to spend $10 on the admission, even if she does not go on any rides or gets any food. So we put 10 where the “b” is. Then each time she gets food or goes on a ride, she pays another $1.25. Therefore, you can plug 1.25 into where the m is. That leaves you with “y=1.25x+10”.
