Answer:14
Step-by-step explanation:
A nickel is 5 cents (20% of dollar)
and a quarter is 25 cents (25% of dollar)
We have given a pile of 42 coins worth of $4.90
Let x be the no nickels and
y be the no of quarter
therefore
x+y=42 -----1
+
=4.90 ---2
Solving
we get
x=14 & y=28
Therefore no of nickels is 14 & no of quarters is 28
Subtract 43 from both sides
-6p=-30
Divide both sides by -6
p=5
Final answer: p=5
