Problema Solution
Two pan pizzas and two burritos provide 3100 calories. One pan pizza and one beef burrito 1550 calories. How many calories are in each items?
Answer provided by our tutors
Let
x = the calories in one pan pizza
y = the calories in one beef burito
2 pan pizzas and 2 burritos provide 3100 calories means:
2x + 2y = 3100 divide both sides by 2
x + y = 1550
1 pan pizza and 1 beef burrito provide 1550 calories means:
x + y = 1550
y = 1550 - x
