PARRAINGO

Answer:

  • Number of calories in burger = 620 calories
  • Number of calories in hotdog = 400 calories

Step-by-step explanation:

Number of calories in burger = x

Number of calories in hotdog = y

y = x - 220

x + 2y = 1,420

Substitution:

x + 2 * (x - 220) = 1,420

x + 2x - 440 = 1,420

3x = 1,420 + 440

x = 1,860 / 3

x = 620 calories

y = x - 220

= 620 - 220

= 400 calories

The calories in each item are :

  • Number of calories in burger = 620 calories
  • Number of calories in hotdog = 400 calories

Number of calories in burger = x

Number of calories in hotdog = y

Equations:

                 y = x - 220--------------1

                 x + 2y = 1,420----------2

Substitution:

  • x + 2 * (x - 220) = 1,420
  • x + 2x - 440 = 1,420
  • 3x = 1,420 + 440
  • x = 1,860 / 3
  • x = 620 calories

Putting Value of x in equation 1.

  • y = x - 220
  • y = 620 - 220
  • y = 400 calories

Therefore, the calories in each item are the number of calories in burger is 620 calories and number of calories in hotdog is 400 calories.
