Question

Choc-arcade has two of Elijah's favorite things: Chocolate shop and arcade! not only,but Choc-arcadesloyalty program rewardsElijah with free game tokens every time he buys chocolate There is a proportional Bishop between the number of chocolates Elijah buys,x and the number of free game tokens he gets,y What is the constant of proportional?

Answer 1

Number of chocolates = x

Number of tokens = y

Proportional equation:

y = kx

Where:

k: constant of proportionality

By looking at the graph, we can see that there is a coordinate point (x,y), which is (5,10)

Replace x, y by the coordinate point from the graph and solve for k:

10= 5k

10/5= k

2= k

Constant of propotionality : 2
