Answer:

Valek did not correctly divide 1,536 by 20 going from step 3 to step 4. Valek did not find the correct product of 32 and 48 going from step 2 to step 3. Valek should have written the proportion in step 1 as 32/20 = PR/48.

There are 3 women and 3 men waiting for the lift on the ground floor in the building of 10
LenKa [72]

Two problem questions for the default cases could be:

  • How many floors can the elevator go up if each person gets off on a different floor?
  • If two couples get off on floors 4 and 6, respectively, how many couples are left in the elevator?

<h3>How to create questions?</h3>

To create problem questions about a topic, we must take into account the data we have about that problem in order to pose a question that expands our knowledge about it or that is adapted to the information we already know.

According to the above, in the case of couples and individuals waiting in the elevator, we must create questions taking into account the hypothetical cases in which there are 3 couples and 6 separate people.

So, the questions we can create are:

  • How many floors can the elevator go up if each person gets off on a different floor?
  • If two couples get off at the 4th and 6th floors, respectively, how many couples are left in the elevator?

Can someone please help me with this question?
Natasha_Volkova [10]
Hi there!

First, let's use a proportion to figure out the commission the salesperson makes. 

WORK:
x/15486 = 3/100
100x = 46458
x = 464.58 (commission)

Next, we'll add together the commission and her salary.

WORK:
464.58 + 1200 = 1664.58

ANSWER:
$1664.58


Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
