Mrs. Harris gave a quiz in math class. The table below shows the relationship between the number of correct answers and the student’s grade. What is the constant of proportionality (points per question) for the quiz? *

I am pretty sure it's 2.5 because my little sister got the question and I helped her with it!

Step-by-step explanation:

proof it's 2.5 !

divide y by x and you get 2.5

this is the answer and if you try to prove me wrong your a meanie

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
