Question

ava finds some dimes and quarters in her change purse. how much money (in dollars) does she have if she has 11 dimes and 12 quarters how much money in dollars does she have if she has x dimes and y quarters?

Answer 1

How much money (in dollars) does she have if she has 11 dimes and 12 quarters?: $4.10

How much money in dollars does she have if she has x dimes and y quarters?: 10x+25y=$?

(There are no numbers for the second one so there is no way to determine the amount of money. Therefore, it is an equation.)

Work:

11x10=110

110/100=1.10

25x12= 300

300/100=3

1.10+3=4.10

Hope this helps :)
