Ответ:
$2.50
Step-by-step explanation:
We can set up a system of equations, where p is the price of one pack of pens and b is the price of one binder.
3p + 4b = 16.75
2p + 5b = 17
We can solve by elimination by multiplying the top equation by -2 and multiplying the bottom equation by 3.
-6p - 8b = -33.5
6p + 15b = 51
Add them together:
7b = 17.5
b = 2.5
