PLS HELP I'M STUCKKK AND PLS EXPLAIN! WILL MARK BRAINLIEST!! :)

Answer:
p=49 n=76 (b)
Step-by-step explanation:
p+n=125
p+3.52n=316.52
Therefore:
p=125-n
Now if we plug in for p
125-n+3.52n=316.52
Now solve
-125 both sides and simplify=
191.52 = 2.52n
Now divide
n=76.
Now plug in 76 for the top one
p+76=125
Simplify=
p=49
Hope this Helped <3
Answer:
A
Step-by-step explanation:
Let's subract both these equations.
P+N = 125
and
P+3.52N = 316.52
2.52 = 191.52
191.52/2.52 = 76
P = 76
76 + N = 125
N = 49
Check:
49 + 76 = 125
Answer is A
