Clare knows that Priya has a bunch of nickels and dimes in her pocket and that the total amount is $1.25. Find one possibility for the number of nickels and number of dimes that could be in Priya's pocket. Write an equation that describes the relationship between the number of dimes and the number of nickels in Priya's pocket. Explain what the point (13,6) means in this situation. Is the point (13,6) a solution to the equation you wrote? Explain your reasoning.

Final answer:

One possible solution for the number of nickels and dimes that Priya could have is 5 nickels and 10 dimes, described by the equation 5N + 10D = 125. The point (13,6) means Priya has 13 nickels and 6 dimes, which is also a solution to this equation.

Step-by-step explanation:

To find one possibility for the number of nickels and dimes Priya has, we will let the number of nickels be represented by N and the number of dimes by D. Since one nickel is worth 5 cents and one dime is worth 10 cents, the total value of the nickels and dimes can be expressed in cents as 5N + 10D = 125. This equation describes the relationship between the number of dimes and the number of nickels in Priya's pocket.

One solution to this equation is N = 5 and D = 10 because 5(5) + 10(10) = 25 + 100 = 125 cents or $1.25. Now, let's examine the point (13,6): this point represents having 13 nickels and 6 dimes. To verify if this is a correct solution, we plug these values into our equation: 5(13) + 10(6) = 65 + 60 = 125. Since this also equals $1.25, the point (13,6) is indeed a solution to the equation.

Answer:5x + 10y = 125

Step-by-step explanation

Number of nickel = x

Number of dime = y

Nickel = 5 cent

Dime = 10 cent

Total value = $1.25

Total value should be converted to cent since both dime and nickel are both in cent

= $1.25 * 100 = 125 cents

Therefore,

5x + 10y = 125 cents
