Answer:
$300
Step-by-step explanation:
Let D = Dave's savings and S = Sam's savings.
(1) D/S = 5/4
(2) (D – 40)/(S-40) = 13/10 Multiply (1) by 4S
(3) 4D = 5S Multiply (2) by 10(S-40)
10(D - 40) = 13(S - 40) Remove parentheses
(4) 10D – 400 = 13S - 520 Solve (3) for S
S = (4/5)D Substitute into (4)
10D – 400 = 13(4/5)D - 520 Multiply each side by 5
50D – 2000 = 52D – 2600 Subtract 50D from each side
-2000 = 2D – 2600 Add 2600 to each side
600 = 2D Divide each side by 2
D = $300
Dave's savings at first were $300.
1. Know the Exam
You’ve studied and you know the material, but have you taken the time to look at the actual exam? Taking the time to look at the exam itself will help you to learn more about the details of the HESI exam and what you can expect when you take the actual exam.
Here’s what you need to know about the HESI test:
2. Read Everything Carefully
The HESI exam can be a tricky test, so it is important that you read carefully the entire question as well as all of the answers. Often times, the test writers will throw in a few tricks to distract you and to keep you from seeing the correct answer. They may throw in an answer or two that could seem correct but is not necessarily the “best” answer.
3. HESI Flashcards
Flashcards come in handy when you need to get right down to the detail of the concepts that you need to study. Not only will using flashcards to study help you get right down to the details, but they also help you remember more information for the long-term. Using flashcards will come in very handy when you’re studying for the vocabulary section of the HESI test.
4. Know That There Is No “Pass” or “Fail”
The HESI exam is scored on a scale ranging from 750 to 900, with 900 being the best score possible. While you don’t actually “pass” or “fail” the HESI exam, every school has their own set score, and which subtests, are required for admittance into the progress
5. Create a Study Schedule
Don’t wait until the last minute to start studying for your HESI exam. Once you have scheduled your test date, sit down and create a study schedule that you can stick with leading up until right before the test. Also, instead of cramming the night before the exam, use this time to get a good night’s sleep so you will be refreshed and ready for the exam the next day.
6. HESI Practice Test
The only way you’re going to really know which areas you’re going to need work in is to take a HESI practice test. Not only will this give you an advantage of knowing which area you need more work in, but you will also get a feel of the real exam. When you’re ready to take a practice test, check out our HESI Practice Test.
7. Find Out Which Tests You Need
Many nursing schools require their applicants to take every section of the HESI exam. However, there are also many schools and programs that do not require every section to be completed. Make sure to check with the nursing school that you wish to attend to see about which sections of the HESI exam you will need to take. This way you can properly prepare for them.
8. Take The Individual Tests in Order from Easy to Difficult
You’re not required to take the individual tests in a specific order, you can choose which section you want to take first. In this case, take the sections of the exam that are easier for you and leave the more difficult sections for a later date. Not only will this give you more time to study for the more difficult section of the HESI exam, but you’ll be able to get some of the easier sections out of the way.
10. Check Your Answers
The HESI test as a whole is timed. However, the individual sections are not. This means that you can spend as much time as you need to on an individual section. Since you’re not timed during individual exams, you can go back and check your answers to make sure you didn’t make any mistakes. This will be very important when it comes to the Mathematics section.
