Question

The original price of a bicycle was $150.00. Jeremy bought the bike at a time when the store was having a 20%-off clearance sale.
What was the price of the bicycle when Jeremy bought it?
$140.00
$149.80
$130.00
$120.00

Answer 1

Answer:

$120

Step-by-step explanation:

Multiply the price of the bike by the discount percentage

150 * 0.20 = 30

Subtract the number you just found from the original price

150 - 30 = 120

There is your answer

You could take a shortcut by doing the following

1 - 0.20 = 0.80

Then multiply the original value by the new percentage

150 * 0.80 = 120

Personally I like the first method because it makes more sense.

Answer 2

Answer:

The answer is $120.00

Step-by-step explanation:

So first from the problem; The original price is:

$150.00

The percent off clearance:

20%

You can do this two ways:

1. $150.00*20% or 0.2= $30.00

$150.00-$30.00= $120.00

2. $150.00/20% or 0.2= $750.00

$750.00-$150.00-$600.00

$600.00*20% or 0.2= $120.00

You can do it both ways, and it will still be right.
