Answer:

The decrease in percent is 50 %

Step-by-step explanation:

Initial point is 90 while the final point is 45. We need to find the percent decrease. Percent change is given by :

\% =\dfrac{\text{change}}{\text{original amount}}\times 100

\% =\dfrac{90-45}{90}\times 100

\%=50\%

So, the percent decrease is 50 percent. Hence, this is the required solution.

Answer:

A)

x=  the number of ride tickets

y=  the total cost of admission plus how many ride tickets a person purchases

B)

y= 1.25x + 9.5

C)

It is a$1.25 per ticket for the rides at the fair, so it would be 1.25 multiplied by the amount of tickets that are purchased (x). Spencer bought 17 tickets, so 17x1.25= 21.25 and it says that he spent a total of $30.75 at the fair, so 30.75-21.25=9.5, so that means the cost of admission is $9.50.

Step-by-step explanation:

I hope this helps!
