Answer:

  • 35 grams

Step-by-step explanation:

Let s be the amount of carbohydrates in snickers bar and t be the amount of carbohydrates in thin bar

Then we have below system of equations

  • 2s  + t = 70
  • s + 2t = 35

Subtract the second equation from the doubled the first equation:

  • 2(2s + t) - (s + 2t) = 2(70) - 35
  • 4s - s + 2t - 2t = 140 - 35
  • 3s = 105
  • s = 105/3
  • s = 35 g

Finding t:

  • 3*25 + t = 70
  • 70 + t = 70
  • t = 0 g

Snickers bar has 35 grams of carbohydrates
