A bike costs $650.00. Then it is marked down 35%

Vsevolod [243]

Answer:

$422.50

Step-by-step explanation:

If the bike is marked down by 35% then the final sale price will be 65% of the original price (since 100% - 35% = 65%).

Convert 65% into a decimal: 65% = 65/100 = 0.65

Therefore, 65% of $650 = 0.65 × 650 = $422.50
