To add the bushes and trees, to get 19 bushes and 6 trees, but this wouldn't get me anywhere, because I don't have subtotals for the bushes and trees.
So I'll pick variables (b for the number of bushes and t for the number of trees) and set up a system of equations:
first order: 13b + 4t = 487
second order: 6b + 2t = 232
Multiplying the second row by –2, I get:
13b + 4t = 487
–12b – 4t = –464
This says that b = 23.
Back-solving, I get that t = 47.
Of course, the exercise didn't ask for the values of the two variables. Translating back into English, the solution is,
each bush is $23 and each tree is $47.
