Hi Serena, let x represent the grams of carbohydrates in the chicken sandwich. Then the pasta salad had 2x + 30 grams of carbohydrates.
Equation to solve:
x + (2x + 30) = 150
3x + 30 = 150
3x = 120
x = 40
The chicken sandwich had 40 grams of carbohydrates.
The pasta salad had 2 * 40 + 30, or 110 grams of carbohydrates.
