Question

At a particular restaurant, each pizza roll has 70 calories and each mini hotdog has 60 calories. A combination meal with mini hotdogs and pizza rolls is shown to have 1140 total calories and twice as many mini hotdogs as there are pizza rolls. Write a system of equations that could be used to determine the number of pizza rolls in the combination meal and the number of mini hotdogs in the combination meal. Define the variables that you use to write the system.

Answer 1

Let "p" represent the number of pizza rolls in the combo meal

And let "m" represent the number of mini hot dogs in the combo meal

If you want to know the number of calories in the combo meal consisting of pizza rolls and mini hot dogs then you would multiply the number of pizza rolls (p) by 70 and the number of mini hot dogs (m) by 60 and add them up so:

70p + 60m = 1140

Also, since there are "twice as many mini hotdogs as there are pizza rolls" then you would double the number of pizza rolls to get the number of mini hot dogs so:

2p = m

Those are the two equations in the system of equations and the variables are defined above as well.
