At a school carnival, tickets can be purchased to participate in different activities. The table shows the total cost for different numbers of tickets.

8 | 2.00
12 | 3.00
20 | 5.00
30 | 7.50
50 | 12.50
What is the constant of proportionality that relates y, the total cost in dollars, to x, thenumber of tickets purchased?

0.25

Step-by-step explanation:

Here, we want to find the constant of proportionality that relates total cost in dollars to number of tickets purchased

Mathematically, that will be ;

7.50/30 = 1/4 = 0.25

Kindly note we can select any pair

The ratio of both at any point in time is constant

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
