Answer:
It would be difficult to factor it...
Step-by-step explanation:
I'm not sure factoring would work so the quadratic formula would be the only way
(30.26/35.6)*100= 85%
check: .85 * 35.6 = 30.26
25*2=50
10*5=50
so 2 packets of envelopes and 5 packets of stamps
The answer is 24/5 or 4 4/5 but if it is 11 on 5, the answer would be 44/5 or 8 4/5
