Step 1
Given that Tyler bought 5 cups of hot cocoa and 4 pretzels for $18.40 and then for his family members who wanted a second serving bought 2 cups of hot cocoa and 4 pretzels for $11.20.
We can take the cost of 1 cup of cocoa to be c
and
The cost of 1 pretzel to be p
Then we can have the system of equations as
Step 2
Find what c,p represents in the solution to the system of equations.
