The step work of the question along with the answer​
Travka [436]

Answer: RM 31631

Step-by-step explanation:

We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:

RM 57000(\frac{8}{9})^{n}

Where RM 57000 is the price of the car when it was bought new, and n=5 is the number of years the car was used.

Solving the formula with the given data:

RM 57000(\frac{8}{9})^{5}=RM 31630.95 This is the value of the car according to the formula.

However, this value can be approximated to:

RM 31631

a suit is being sold at a 20 % off (discount). The sale price is $ 270. What was the original price ?
Lisa [10]

Answer:

The original price is 337.50

Step-by-step explanation:

If we get 20% off, we still have to pay 100-20 =80%

Let x be the original price

x *80% = 270

.80x = 270

Divide each side by .80

.80x/.80 = 270/.80

x =337.50

The original price is 337.50
