Alexxx [7]

Answer: The first machine would cost $420

and the second machine would cost $432

Machine 2:  A 10% discount means you pay 90%

600(.90) = 540   But now you get a 20% discount on that amount, which means you would pay 80%

So, 540(.80) = 432

Find the original price if the sale price of the cell phone is $205.50
Arlecino [84]

Answer:

$293.6

Step-by-step explanation:

Here is the complete question: A cell phone is on sale for 30% off. Find the original price if the sale price of the cell phone is $205.50.

Given: Sale price of cell phone is $205.50

           Discount= 30%

As 30% discount is given on original price or we can say 70% of original price is $205.50.

∴ Let the original price be x.

⇒ \frac{70}{100} \times x= 205.50

Now, cross multiplying both side.

⇒ x= \frac{100}{70} \times 205.5

∴ x= $293.6

The original price of cell phone is $293.6.
