Answer:

She has 11 dimes and 17 nickels

Step-by-step explanation:

dimes --- d

nickels -- n

Equation with number of coins: 
n+d = 28
n = 28-d

10d + 5n = 195


Divide by 5

2d + n = 39

sub in the other equation:

2d + 28-d = 39
d = 11
n = 28-11 = 17

She has 11 dimes and 17 nickels

check:

total = 11 + 17 = 28 , check!

value: 10(11) = 5(17) = 195 , check!
