Question

Andrew purchased some drinks and some chips. Each bag of chips cost $2.00 and

each drink cost $2.50. The expression 2x + 2.5y gives the total amount of money
spent by Andrew on chips and drinks. What is the meaning of the term 2.5y?

Answer 1

2.5y=amount spent on drinks

Explanation:

If chips are $2 and drinks are $2.50 and we do not know how many he bought of each, we put this into an equation which is

2x+2.5y

x=number of bags of chips while the 2 is two dollars per bag

so, if he bought 2 bags of chips 2(2)= $4 spent.

y= number of drinks and 2.5 is $2.5 per drink, so if he bought 4 drinks:

2.5(4)= $10 spent on drinks.
