Find the number of grams of carbohydrates for both

Question

A meal of a chicken sandwich and some pasta salad had 150 grams of carbohydrates. The pasta salad had 30 grams more than twice the grams of carbohydrates in the chicken sandwich. Find the number of grams of carbohydrates for both

Answer 1

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.
