After allowing 20percent discount and levying 13percent vat the value of a watch will be rs 904 what is the marked price of watc

Eddi Din [679]

9514 1404 393

Answer:

₹1000

Step-by-step explanation:

Let m represent the marked price. After the discount, the price is 0.80m. After the tax is added, the price is (0.80m)(1.13). This value is Rs 904, so the marked price is ...

(0.80m)(1.3) = ₹904

m = ₹904/(0.80×1.13) = ₹904/0.904

m ≈ ₹1000

The marked price of the watch is ₹1000.

Use the formula s - 25,000(1.032) to calculate your salary after 6 years. Round your answer to the nearest dollar

aleksandr82 [10.1K]

Answer:

A) $30201

Step-by-step explanation:

The formula S=25000(1.032)^t describes a 3.2% growth in salary for every year where the principal value is $25000 and the time "t" is the amount of years. This is known as exponential growth.

Since t=6:

S=25000(1.032)^6

S=30200.78

Rounded to the nearest dollar is $30201. So A is the correct choice.
