A. Using algebra

Let

A=number of adults who attended, then

36-A = number of children who attended

19A + 17(36-A) = 646

Solve for A.

B. Using arithmetic

If only adults went, ticket sales would have collected 36*19=$684

For every child who went, sales would reduce by $2.

So number of children=(684-646)/2=19
