The martinez family is going school supply shopping for their kids. Crystal needs 2 binders and 3 notebooks. Daniel needs 1 binder and 1 notebook. If notebooks cost $3 each and they spent $27 total on all items, how much does a binder cost?

$18

Step-by-step explanation:

3(3) = $9

$27 in total

27 = 3(3) + 2x

5$ per binder.

Step-by-step explanation:

3 Notebooks + 1 Notebook = 4 Notebooks. Each notebook cost 3$ and 3x4 = 12 so 12$. 2+1 = 3 so 3 binders. 27$ - 12$ = 15$. 15 / 3 = 5.
