Bethany
has $3.10 in nickels and dimes. She had a total of 44 coins. What is the value of the nickels Bethany has

Answer 1

She would have a 1.30$ in nickles

Answer 2

n + d = 44
.05n + .10d = 3.10
Multiply the first equation by -.10

-.10n - .10d = - 4.4
.05n + .10d = 3.10
Add the equations.
- .05n = - 1.30
Divide both sides by- .05
n = 26
She has 26 nickels * .05 = $ 1.30
