Clare knows that Priya has a bunch of nickels and dimes in her pocket and 2 points
Maurinko [17]

Answer:

5x + 10y = 125

Step-by-step explanation:

Let :

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
