Question

At a particular restaurant, each mini hotdog has 90 calories and each pizza roll has 50 calories. A combination meal with pizza rolls and mini hotdogs is shown to have 860 total calories and 6 more pizza rolls than mini hotdogs. Write a system of equations that could be used to determine the number of mini hotdogs in the combination meal and the number of pizza rolls in the combination meal. Define the variables that you use to write the system.

Answer 1

Let X= # of mini hotdogs
Let Y= # of pizza rolls

90x+ 50y = 860
Since 6 more pizza rolls than mini hotdogs:
y-X=6
System of Equations:
90x+50y = 860
y-X-6
