My pennies are worth as much as my nickels, my nickels are worth as much as my dimes, and my dimes are worth as much as my quarters. If the value of all these coins is $8, how many nickels do I have

Answer: 40

Step-by-step explanation:

NOTE: Let TV represent "Total Value of"

TV Pennies + TV Nickels + TV Dimes + TV Quarters = $8.00

since TV Pennies = TV Nickels = TV Dimes = TV Quarters

then 4 (TV Nickels) = $8.00

⇒ TV Nickels = $2.00 divided both sides by 4

since a nickel has a value of $0.05,

then $0.05x = $2.00 "x" represents the quantity of nickels

⇒ x = 40 divided both sides by $0.05

One hundred and sixty
