1 answer:
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.

Let x represent the total number of chocolate cups and y represent the total number of vanilla cups Beth buys.
She needs a total of 24 ice cream cups. So, the equation can be written as:
The number of chocolate cups she needs are twice as compared to vanilla, so we can write the equation as:
Case 1:
Only constraint 2 would be met if 9 vanilla cups and 18 chocolate cups were purchased.
This is because the number of chocolate cups are double as compared to vanilla cups but the total number of cups in this case is not 24. So constraint 1 is not met.
Case 2:
Only constraint 1 would be met if 6 vanilla cups and 18 chocolate cups were purchased.
This is because the total number of cups in this case is 24 but the chocolate cups are three times as compared to the vanilla cups. So the constrain 2 is not met in this case.
