Question

How do I setup this problem?? I need some help please!!

Answer 1

I'd say a good problem would be 5n+10d=125

Answer 2

Answer: 7 nickels and 10 dimes

Step-by-step explanation:let

n = amount of nickels

d = amount of dimes

n + d=16---(1)

For the second equation, we know that a dime is worth 10¢ and a nickel is 5¢, so it should be:

5n + d =125

(n+2d)=25

n+2d=25----(2)

Equation (1) - (2)

n+d-n-2d=16-25

d=9-----(3)

Substituting value of d from equation (3) to (1)

n+9=16

n=7
