the aquarium charges $16 for adult admissions and $10 for each child. The aquarium bill for a school field trip was 502$ Write a linear equation in general form to represent this situation. Let C represent the number of children and A represent the number of adults attending the field trip.____if 39 children attended the field trip how many adults were there?______Adults

Respuesta :

$16 per adult, $10 per child, Total of $502

The number adults multiplied by the cost for adult plus the number of children multiplied by the cost for children is 502:

First answer:

16A + 10C = 502

If C = 39:

16A + 10(39) = 502

16A = 502 - 10(39) = 502 - 390 = 112

16A = 112

A = 112/16 = 7

A= 7

Second answer:

7 adults
