Since .25*10 is 2.50 and .10*15 is 1.50 it equals $4. So the ratio is 10:15 which turns to 2:3 ratio simplified.

Let x = # of quarters // Let y = the # of dimes

25x + 10y = 400

x + y = 25

Using these two equations, we can make a system to solve. The formatting on Brainly makes it hard to write on here, so I'll just handwrite it.

Basically, the answer is 3:2.
