Tanya has 44 quarters and dimes worth$8.30. how many of each type of coin does she have

Answers

Answer 1

Answer:

Tanya has 26 quarters and 18 dimes.

Given that Tanya has 44 quarters and dimes which worth $8.30, we need to find the number of each coin type,

To find the same we will use the concept of system of Linear equations,

Let's solve this problem step by step.

Let's assume Tanya has x quarters and y dimes.

The value of x quarters is 25x cents.

The value of y dimes is 10y cents.

According to the given information, the total value of the quarters and dimes is $8.30, which is equivalent to 830 cents. So we have the equation:

25x + 10y = 830 ...........(Equation 1)

Tanya has 44 coins in total:

x + y = 44 ...........(Equation 2)

Now, we can solve this system of equations (Equation 1 and Equation 2) to find the values of x and y.

Multiplying Equation 2 by 25, we get:

25x + 25y = 1100 ...........(Equation 3)

Subtracting Equation 3 from Equation 1, we eliminate the x term:

25x + 10y - (25x + 25y) = 830 - 1100

-15y = -270

Dividing both sides by -15, we get:

y = (-270)/(-15) = 18

Substituting the value of y back into Equation 2, we can find x:

x + 18 = 44

x = 44 - 18 = 26

Therefore, Tanya has 26 quarters and 18 dimes.

Answer 2

Answer: Suppose Tanya has d dimes worth 10d cents and (44-d) quarters worth 25(44-d)
cents. Now total value = 830 cents, ie., 10d + 25(44-d) = 830, ie., 1100 -830 = 15d, ie., d = 54/3 = 18. Therefore A has 18 dimes and 26 quarters.

The doublePennies() function is an illustration of a recursive function in Java

How to complete the doublePennies() function?

The base case of the doublePennies() function is that:

When the number of days is 0, then the total available pennies is the same as the total number of pennies.

The algorithm of the above highlight is:

if numDays equals 0 then

totalPennies = numPennies

Using the above algorithm, the complete base case is:

if(numDays == 0){

totalPennies = numPennies;

}
