Answer:
16 nickels thicker
Step-by-step explanation:
You would need 20 nickels for 1 dollar and only 4 quarters for 1 dollar. Do 20 minus 4 and your answer is 16 nickels. The stack of nickels is 16 coins thicker. Hope this helped!
3000/100 = 30. When you go from Centimeters to Meters you divide by 100.
I believe it's not a function because the input (x) 4 has two outputs(y), 2 and 8.
