Answer:
A corn dog: $2.75
A candy bar: $1.00
Step-by-step explanation:
The missing question is: " What was the price of a corn dog and the price of a candy bar?"
Let be "d" the price in dollars of a corn dog and "b" the price in dollars of a candy bar.
Set up a System of equations:
[tex]\left \{ {{d+3b=5.75} \atop {2d+2b=7.50}} \right.[/tex]
You can use the Elimination method to solve the System of equations. The steps are:
1. Multiiply the first equation by -2.
2. Add both equations.
3. Solve for "b".
Then:
[tex]\left \{ {{-2d-6b=-11.5} \atop {2d+2b=7.50}} \right.\\...........................\\-4b=-4\\\\b=\frac{-4}{-4}\\\\b=1[/tex]
4. Substitute the value of "b" into any original equation and solve for "d" in order to find its value:
[tex]d+3(1)=5.75\\\\d=5.75-3\\\\d=2.75[/tex]
