A store allows customers to fill their own bags of candy. Solve.

A store allows customers to fill their own bags of candy. Troy decides he only wants chocolate-covered pretzels and gumdrops. Chocolate-covered pretzels sell for $0.89 per pound, and gumdrops sell for $0.65 per pound. Troy’s bag weighs 1.8 pounds and it cost $1.29.

Answer

What do we know in this problem?

  • What types of candy are involved and how much each of them costs. 
  • What is the total weight and the total cost.

 

What do we want to know? 
  • How much of each kind of candy were bought. 
This means that we have two variables and thus we need two equations to solve.
Start by identifying the variables, then find ways to create equations using these variables.

 

Example:

Let p be the amount of pretzels and g be the amount of gumdrops.

Since the bag weighs 1.8 pounds, we know that p + g = 1.8

Since it cost him $1.29 and we know the individual costs, we also know that .89p + .65g = 1.29

With those two equations you can use various techniques to solve the problem.
