Question

Mark wants to buy a new lap top computer. He finds one that was priced

at $1200.00. It is on sale for 25% off. What is the sale price of the lap
top?

Answer 1

The total for the laptop would then be 900$

Answer 2

sale price: $900

Step-by-step explanation:

original price will be always of 100%

sale price: 100% - 25% = 75%

so solve:

100% ↔ $1200

1% ↔ $1200/100

1% ↔ $12

75% ↔ (12 * 75) = $900
