Katie gave melanie $2.45 in dimes and nickels. if 10 coins were dimes how many coins were nickels? which equation models this problem? a. 2.45 • 10 - 5n b. 0.05n + 2.45d = 10 c. 10 • 0.10 + 0.05n = 2.45 d. 0.05 • 10 + 0.1 • d = 2.45

C. 10 • 0.10 + 0.05n = 2.45

Step-by-step explanation:

Let n be the number nickels and d be the number of dimes,

Since, 1 nickel = $ 0.05,

1 dime = $ 0.10,

Thus, the total value of n nickels and d dimes  = 0.05n + 0.10d

According to the question,

0.05n + 0.10d = 2.45 ----(1)

d = 10 ----(2)

From the above equation,

Hence, OPTION C is correct.

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
