Hello!
Let's write some important information contained in the exercise:
• hotdogs: $2.59 (,x,)
,
• hamburgers: $5.29 (,y,)
He needs 11 packages. Let's write it:
• x + y = 11
He spent a total of $39.29. We can write it as:
• 2.59x + 5.29y = 39.29
Now, let's solve these two equations as a linear system:

First, let's isolate x in equation A:

Now, we will replace where's x by 11-y in equation B:

As I called the hamburgers as 'y', we know that he bought 4 packages of hamburgers.
<h3>Answer: 36%</h3>
============================================
Explanation:
There are 20 blue cards out of 10+20+25 = 55 cards total.
Divide the 20 over 55 to get
20/55 = 0.363636...
where the "36"s go on forever
So 20/55 = 0.3636 approximately
Move the decimal point over 2 spots to go from 0.3637 to 36.37%
Then round to the nearest percent: 36.37% ---> 36%
The probability of getting a blue card is approximately 36%
Answer:
C ($19.25)
Step-by-step explanation:
First, find how much 1 carton costs, which is $8.75 divided by 5, which is $1.75. So, to find how much 11 cartons cost, we just multiply by 11 to get [tex]\boxed{\$19.25}[\tex]
