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

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

$d + n =175$

$d = 175-n$

And the second equation is

$0.05n + 0.1 d= 13.30$

Substituting the value of d, we will get

$0.05n +0.1(175-n)=13.3$

Correct option is the last option .
