    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
