Your procedure is perfect, you're fine, however, bear in mind that, in a calculator when plugging in values for some functions, specially trigonometric ones, if you tell it cos(40), and the calculator is in Radian mode, it thinks you meant cosine of 40 radian units, if you give it cos(40) and it's in Degree mode, it thinks you meant 40°, and 40 radians is hugely different than 40°.

so, make sure your calculator is in Degree mode, as you'd have guessed, it isn't.

12.) You purchased a scooter for $6,800 when it was on sale for 30% off. What was the original price of thescooter?

Rina8888 [55]

SOLUTION:

Case: Percentages

Method:

The sale price after 30% off is $6800

Let the original price be 'x'

30% off means 70% of the original price

$\begin{gathered} \frac{70}{100}\times x=6800 \\ 0.7x=6800 \\ x=\frac{6800}{0.7} \\ x=9714.2857 \end{gathered}$

Final answer: (Nearest cents)

The original price was $9714.29

Karen works for 85 hours throughout a two-week period. She earns $2,891.25 throughout this period. How much does karen earn for

valentinak56 [21]

$271.11 or $271.12 if you round up. Not sure how this one is complicated. Correct me if I’m wrong... 2.891.25 divided by 85. You then take that number and multiple it by 8. Seems very straight up.

Ralph Chase plans to sell a piece of property for $170000. He wants the money to be paid off in two waysminusa short-term note

PSYCHO15rus [73]

Answer:

Amount of short term note = $90,000

Amount of long term note = $80,000

Step-by-step explanation:

Data provided in the question:

Total amount = $170,000

Interest rate of short term note = 10%

Interest rate in long term note = 8%

Total annual interest paid = $15,400

Now,

Let the amount of short term interest be 'x'

thus,

amount of long term interest will be ($170,000 - x)

also,

Interest on short term note + Interest on long term note = Total interest

⇒ 0.10 × x + 0.08 × ($170,000 - x) = $15,400

0.1x + $13,600 - 0.08x = $15,400

0.02x = $15,400 - $13,600

0.02x = $1,800

⇒ x = $90,000

Hence,

Amount of short term note = $90,000

Amount of long term note = $170,000 - $90,000 = $80,000
