Brooklyn has a combination of dimes and nickels in her wallet she has three times as many nickels as she does dimes and the total value of the coins is 4.00 how many does she have of each coin

she has 16 dimes and 48 nickels

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a nickel is 5 cents. Converting to dollars, it becomes

5/100 = $0.05

Let x represent the number of dimes that she has in her wallet.

Let y represent the number of nickels that she has in her wallet.

she has three times as many nickels as she does dimes. This means that

y = 3x

the total value of the coins is $4.00. This means that

0.1x + 0.05y = 4 - - - - - - - - - - - 1

Substituting y = 3x into equation 1, it becomes

0.1x + 0.05 × 3x = 4

0.1x + 0.15x = 4

x = 4/0.25 = 16

y = 3x = 3 × 16

y = 48
