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.
the pasta and the chicken come up to 150grams so... P+C=150
we also know that the pasta is 30 more (added) than twice(multiplying) the grams as the chicken. P= 30+ 2C
so we have to take that and substitute into our first problem so that it looks like this.
(30+ 2C)+C=150 30+3C=150
now we're going to find the grams of "C"
30+ 3C= 150 3C=120 C=40 gram
so the chicken has only 40 grams we know that together the pasta and chicken came to 150 gram so by doing some simple subtraction we see that the pasta had 110 grams
