Anna has 62 nickels and dimes. If the total value of her coins equals $4.45, how many nickels and dimes does she have?
Let N be the number of nickels Anna has and D be the number of dimes. We know that N + D = 62 and 0.05N + 0.10D = 4.45.
We can multiply the first equation by 0.05 to find that 0.05N + 0.05D = 3.1.
Subtracting the first equation from the second equation, we get 0.05D - 0.05D + 0.10D - 0.05D = 4.45 - 3.1
Combining like terms, we get 0.05D = 1.35
Dividing both sides by 0.05, we get D = 27.
Substituting this value back into the equation N + 27 = 62, we get N + 27 - 27 = 62 - 27
Combining like terms, we get N = 35.
Thus, Anna has 35 nickels and 27 dimes. Answer: \boxed{35, 27}.
