My jar has 25 dimes and some quarters, nickels, and pennies. the number of quarters plus dimes equals the number of pennies. i have 4 nickels for every dime and 2 pennies for every nickel. how many quarters are there? a. 175 b. 150 c. 125 d. 75

Quarters = 175

Step-by-step explanation:

Let the number of dimes in the jar = 25

number of Nickels = n

number of quarters = q

number of pennies = p

Now we will form the equation

Number of quarters plus dimes equal the number of pennies.

q + 25 = p  (1)

You have 4 nickles for every dime

n = 4d

n = 4 × 25 = 100

and you have 2 pennies for every nickels

p = 2n

p = 2 × 100 = 200

Now we replace p = 200 in equation (1)

q + 25 = 200

q = 200 - 25

q = 175

Option A. 175 will be the answer.
