The presented variable would be 8 bags of sweets, 45 dollars, and 3 bags of sweets where in the cost for 3 bags of sweets is what we are looking for. Taking as to how the variables are presented in the problem, it is safe to assume that 8 bags of sweets and 45 dollars go together. Thus, the following ratios will be utilized:

8 bags of sweets is to 45 dollars OR 8:45

3 bags of sweets is to? dollars OR 3:?

let us establish that the unknown is equal to x. The equation then would look like this:

8:45 = 3:x

We then convert these ratios to fractions.

8/45 = 3/x

Then cross multiply.

8x = 215

Solve

8x / 8 = 215 / 8

x = 26.875

or we round it off to its hundredths which is

x = 26.88

So the cost for 3 bags of sweets would be 26.88 dollars.
