Question

the sanctuary is open to visitors. Admissions cost $12 for an adult and $7 for a child. A group of adults and children paid $97 to visit. There were 3 more children than adults. How many children and adults were?

Answer 1

12a + 7c = 97---->12a + 7(a + 3) = 97

c = a + 3 12a + 7a + 21 = 97

19a = 76

a = 4, c = 7

There were 4 adults and 7 children.
