Answer:
Please see below.
Step-by-step explanation:
First, let us find the cost of ONE soft drink.
We have the relation:
4 drinks for $2.20
We can divide the amount of money by the amount of drinks.
2.20 / 4 = 0.55
With this, we can conclude that each drink costs $0.55
A.)
Fill in the table.
For this, we just need simple multiplication.
1 drink = $0.55
2 drinks = $1.10
3 drinks = $1.65
4 drinks = $2.20
B.)
What is the constant of proportionality?
We have y = 2.20 and we have x = 4. Using the equation of proportional relationship, y = kx, we can plug in these numbers.
The constant of proportionality is 0.55.
C.)
If you were to buy 22 soft drinks, how much would it cost?
We can use multiplication.
22 x 0.55 = 12.10
22 soft drinks cost $12.10.
I hope this helps you. Please inform me of any mistakes.
