Rosa has 15 quarters and 10 nickels.
Each can of juice costs 35 cents.
We want to find out how many cans of juice she bought.
Rosa gave the cashier 10 quarters so she has 5 quarters left.
10 quarters equals to about $2.50
Rosa gave the cashier 6 nickels, so she has 4 nickels left.
6 nicks equals 30 cents.
Let's add up the total amount of money Rosa paid the cashier.
$2.50 (quarters) + $0.30 (nickels) = $2.80 (total paid to the cashier)
Now, we know each drink is $0.35, and Rosa paid $2.80 to the cashier.
Simply divide $2.80 by $0.35
$2.80 (total amount paid) ÷ $0.35 (per can) = 8 (cans)
Rosa bought 8 cans.
Also, if you need to know how much money Rosa has left:
5 quarters left = $1.25
4 nickels left = $0.20
Rosa has a total of $1.45 left - just enough for 4 more cans of soda.
