A movie theater has increased their ticket prices. They are shown below The graph shows the proportional relationship of the cost of movie tickets. Using the graph determine the constant of proportionality, k.

k = 12

Step-by-step explanation:

Given in the question,

Cost of the the movie tickets is proportional to the number of tickets sold.

Cost of movie tickets (C) ∝ number of tickets sold (T)

C ∝ T

C = kT

Here 'k' is a proportionality constant.

Since, line given in the graph passes through a point (5, 60)

60 = k(5)

k =

k = 12

Therefore, value of proportionality constant is 12.

Step-by-step explanation:

Your equation is 3 × 2

An easy way to solve this is to make it two fractions so we are going to multiply the whole number by the denominator and add it to the numerator

3 ×4 + 3         you have to multiply before adding

12+3 = 15

Now the other fraction

2×9+2           multiply first (PEMDAS)

18+2=20

Now you put that as the numerator

×

Now you multiply the numerators together and the denominators together

15 x 20 = 300

4 x 9 = 36

     now you simplify

8       since 22 and 36 are even you can simplify further
