Answer :
Since Tameka has 30% worth of a dollar. The total value of the coins in her purse = 0.30* $1 = $0.30 or 30 cents
Total worth of coins in Tameka's purse = 30 cents
The coins that are available are 1 cent coin, 5 cents coin (nickel), 10 cent coin (dime) or a 25 cent coin (quarter)
The only possible way for her to have 4 coins that add up to 30 cents is that she has two dimes and two nickels
2 dimes + 2 nickels = 2 *10 + 2* 5 = 20 + 10 = 30 cents
Answer: 2 dimes (10 cent coins) and 2 nickels ( 5 cent coins)
