Dr. Irvine saw 130 patients in one week. The ratio of kids to adults that he saw is 3 to 7. If k

represents the number of kids and d represents the number of adults, which system of equations should be set up to find out how many kids Dr. Irvine saw during the week?

1 answer

We can set up the system of equations as follows:

1) k + d = 130 (since Dr. Irvine saw a total of 130 patients)
2) k/d = 3/7 (since the ratio of kids to adults is 3 to 7)
