Question 925502: I have a question on my Algebra I homework. The question is," Lucy has some coins in her pocket. She has 2 less nickels than quarters and 3 times as many dimes as quarters. If Lucy has no more than 20 coins in her pocket, what is the most quarters she could have?
I am supposed to put it as an inequality. (???)
I am so lost with this problem. If you have any ideas please let me know.
Thanks in advance!!

You can put this solution on YOUR website! Lucy has some coins in her pocket.
She has 2 less nickels than quarters and 3 times as many dimes as quarters.
If Lucy has no more than 20 coins in her pocket, what is the most quarters she could have?
:
let x = no. of quarters
then
(x-2) = no. of nickels
and
(3x = no. of dimes
:
x + (x-2) + 3x =<20
5x =< 20 + 2
5x =< 22
x =< 22/5
x = =<4 quarters (has to be an integer)
that would give us 2 nickels and 12 dimes, a total 18 coins
