Question

Anaika has found 25 coins this week, all quarters and dimes . If total worth of all coins is $4.00, how many of each coin does anakin have?

Answer 1

Answer:

10 quarters and 15 dimes

Step-by-step explanation:

25 = Quarters +  Dimes

Total worth = $4.00 =  0.25* Quarter +  0.1*Dimes

so...

25 = Q + D ,     D = 25 - Q

4 =  0.25*Q + 0.1 * (25 - Q)

4 = 0.25 * Q + 2.5 - 0.1*Q

1.5 = 0.15Q

Q = 10

D = 15
