Answer:
my life sucks so its 3475
Step-by-step explanation:
You can purchase 6 boxes of medical sponges for $0.50.
Step 1:
Divide 300 by 25.00
300/25= 12
So you get 12 boxes for 1 dollar.
We have 50 cents.
Step 2:
Multiply 12 by 0.50
12*.5 = 6
So you can buy 6 boxes for $0.50.
Hope this helps you! (:
