Ethan finds some dimes and quarters in his change purse. How much money (in dollars) does he have if he has 12 dimes and 4 quarters? How much money (in dollars) does he have if he has xx dimes and yy quarters?

So a dime is .10 or 10 cents

a quarter is .25 or 25 cents

12(.10)=$1.2

4(.25)=1

the equations would be

.25(x)

.10(x)

and if you need them combined it would be

.25(x) + .10(x)

:)

the answer is simply just 6n add the two together as they have an n
