Answer:
To determine the proportional relationship equation between the number of boxes of raisins purchased and the total cost, we can use the given information that Dominic buys 10 boxes of raisins for $5. Let's assign variables to represent the number of boxes (x) and the total cost (y).
We know that Dominic buys 10 boxes of raisins, so x = 10. Additionally, we are given that the total cost is $5, so y = 5.
In a proportional relationship, the ratio between the two variables remains constant. To find this ratio, we can divide the total cost by the number of boxes:
y/x = 5/10
Simplifying this ratio gives us:
y/x = 1/2
Therefore, the proportional relationship equation between the number of boxes of raisins purchased (x) and the total cost (y) is:
y = (1/2)x
This equation shows that for every box of raisins purchased, half a dollar is spent.
