Question

Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the number of nickels in the collection?

0.1n + 0.05(n – 175) = 13.30
0.1n + 0.05(175 – n) = 13.30
0.1(n – 175) + 0.05 = 13.30
0.1(175 – n) + 0.05n = 13.30

Answer 1

I don’t see nothing wrong.... with a little bump and grind

Answer 2

Answer: Correct option is the last option .

Step-by-step explanation:

It is given in the question that Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30.

Let the number of dimes be d and number of nickels be n.

So we will get

And the second equation is

Substituting the value of d, we will get

The last option 0.1(175 – n) + 0.05n = 13.30
