One small and one large animal puzzle kit cost $16 altogether. If the large kit costs three times as much as the small kit, how much does each kit cost?
4 and 12
A= large animalpuzzle kit.
a= small animal puzzle kit.
A + a = 16
A = 3a
=================
solve for A and a.
Hint: Since A = 3a, just substitute 3a for the A in the first equation to have 3a + a 16. Then solve for a. With that value, place it into the other equation and solve for A. Post your work if you get stuck.
