VladimirAG [237]

Since Christian sets aside $60 per month for daily coffee, and McDonalds sells coffee for $ 1, and The Bean Sprout sells a cup of coffee for $3, to create an equation that represents the combinations of coffee options that allow Christian to stay in his budget and provide 2 combinations that use his entire budget, 1 combination that would be under budget, and 1 combination that would be over his budget, the following linear equation must be proposed:

 

M + BS = 60

2 combinations using the entire budget =

  • 15 McDonalds + 15 The Bean Sprout = 15 + 45 = 60
  • 30 McDonalds + 10 The Bean Sprout = 30 + 30 = 60

1 combination under budget =

  • 15 McDonalds + 10 The Bean Sprout = 15 + 30 = 45

1 combination over budget =

  • 30 McDonalds + 30 The Bean Sprout = 30 + 90 = 120
