It costs $8 to enter a fair and $3 for each ride. Which of the following equations represents the total cost, y?

1 answer:

4 0

So the 8 dollars to enter the fair is a flat rate that everyone has to pay no matter how many rides they ride. so this would just become +8. the 3 dollars per ride becomes dependent on how many rides you ride. so if you rode 3 it would be 3(3) + 8 . where as if you rode 4 it would be 3(4) + 8. so the equation becomes y = 3x +8, where y is the total amount of money you spend and x is the number of rides you ride.

Answer:

Step-by-step explanation:

You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):

$4=2^2\\3=3\\2=2$

Therefore, we need to include a factor of 3, and two factors of 2 ( $2^2$ ) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.
