Please show work!!

Answer 1

She has 11 dimes and 17 nickels

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!
