Question

Aretha has $0.85 in nickels and dimes. She has 2 more nickels than dimes. How many nickels and dimes does she have? Please help!! and show work

Answer 1

Let N = # of nickels
D = # of dimes

We need to write down two equations with those two variables. What is the equation you can write down from this part of the problem: "She has 2 more nickels than dimes"?

Answer 2

n=d + 2?

Answer 3

correct. Now what's the other equation: "Aretha has $0.85 in nickels and dimes"

Answer 4

n + d= 0.85?

Answer 5

No, n + d is the number of coins.

Answer 6

oh

Answer 7

.10d + 0.05n = 0.85

Answer 8

Yes. Now you have two equations with the two variables. Solve them.

Answer 9

ok

Answer 10

thanks

Answer 11

btw, decimals annoy me. Your second equation will be easier if you write it cents:
5N + 10D = 85
