Question

I really need help understand how to do my math

Answer 1

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

$\begin{gathered} 5c\text{ + }4p=18.40----(1) \\ 2c+4p=11.20-----(2) \end{gathered}$

Step 2

Find what c,p represents in the solution to the system of equations.

$undefined$
