Question

HELP PLEASE! Which equation can be used to solve the following word problem?
Emilio has 6 more nickels than dimes, and the total value of his coins is $2.10. How many nickels does he have? Let n represent the number of nickels.

Answer 1

A.

0.10n + 0.05n + 6 = 2.10




B.

0.10n + 0.05(n + 6) = 2.10




C.

0.10(n + 6) + 0.05n = 2.10



D.

0.10(n – 6) + 0.05n = 2.10

Answer 3

I thought it would be: $0.10+.30+$0.05=$2.10
but i was wrong

Answer 4

Hint

dimes = nickels + 6

d = n + 6

n = d - 6
