Question

A coin collector has $1.85 in dimes and nickels. she has 8 more dimes than nickels. how many nickels does she have?

Answer 1

Let n be the number of nickels. Now we can write the equation:
5n + 10(n + 8) = 185
Next you need to solve this equation to find the value of n.

Answer 2

5n+10n+80=185? is this right once I solved

Answer 3

kropot? am I right

Answer 4

Yes, you are right so far.

Answer 5

15n+80=185 is this right once I collect like terms

Answer 6

Yes, you are still right.

Answer 7

so now I just subtract 80 from both sides

Answer 8

Yes, that is the next step.

Answer 9

15n=105?

Answer 10

Yes, good work. Now divide both sides by 15.

Answer 11

7 I get that diving 105/15

Answer 12

15n/15 = n = 105/15 = 7
So, the number of nickels is 7.

Answer 13

@pphalke Do you understand the last step?

Answer 14

yes I did
