Tom wants to buy a boot that's at a 40% discount but he waits until another 50% discount is added onto it. The boot costs $490 less with the discounts, how much did the boot initially cost?

490/0.5 = 980

980/0.4 = 2450

 

490/(0.5*0.4) = 490/0.2 = 2450

x  * .4   = amount OFF

x * . 6 = price after 40% off

 

 

x * .6  = price after 40% off

 

x * .6  * .5       +    x  *  .4   = 490 

.3 x     + .4x = 490          x = 700 dollars    original price
