Question

Elane has $7.00 total in dimes and nickels in her coin jar. The number of dimes that Elane has is seven less than three times the number of nickels. How many of each coin does Elane have?

Answer 1

Explanation:

Let the number of 50p coins be x

and the number of 25p coins be 2x

Therefore,

Value of 50p coins = 50x p

and value of 25p coins = 2 * 25x p

= 50x p

Total value = Rs 34 = 34 * 100 p= 3400p

According to the question,

50x p + 50x p = 3400 p

=100x p = 3400p

= x = 3400p/100p

= x = 34

Therefore , number of 50p coins =34

and , number of 25p coins = 34 * 2 = 68
