Answer 1

Answer: 48 dimes, 15 quarter

Explanation:

Given

The money is of the net worth of
`\$8.55`

If there is total of 63 coins

Suppose there are
`x` dimes and
`y` quarter

`\therefore x+y=63\quad \ldots(i)\\\Rightarrow 0.1x+0.25y=8.55\quad \ldots(ii)`

Solve (i) and (ii)

`x=48,y=15`

Thus, there are 48 dimes and 15 quarters
