Apurse contains dimes and nickels. the total value of all the coins is, at most, $2.50, and there are at least three of each coin. which of the following systems correctly shows the system that describes the possible number of nickels (n) and dimes (d) in the purse?

< = that means greater than or equal to or less than or equal to

1.n > = 3
d > = 3
0.05n+0.1d < = 2.50

2. n < = 3
d < = 3
0.05+0.1d < = 2.50

3. n < = 3
d< = 3
n + d > = 2.50

4. n> =3
d > = 3
n + d < =2.50
