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

Answer: 0.1(175-n)+0.05n=13.30

Step-by-step explanation: The question is asking you to make and simplify a system of equations.

The 2 equations are:

n+d=175

0.1d+0.05n=13.30.

d=175-n

Solve for n, then substitute into the second equation.

0.1(175-n)+0.05n=13.30

Hope this helps!
