The problem is telling you that the price of each item and that you should use x and y to represent the number of items.  

Therefore the amount of money you would need will be the price of each item times the number of each item.   So if x = the number of sodas and each soda is 1.50, the expression for that part would be 1.50*x.

So if A = the amount of money you will need you get:$$A=1.50x + 2.00y$$

????? not at all im so confused

If a soda costs $1.50...2 sodas will cost 3.00 right?  That's because the total will 1.50 * number of sodas....or 1.50*x with x just being a variable representing the number of sodas.

Do the same thing for the pretzels to get 2.00y

So the amount will be 1.50*x + 2.00*y where x = the number of sodas bought and y = the number of pretzels bought.

I'm not sure how to explain it any further.
