Question

Suppose an electronics retailer advertises a 30% discount on laptop computers. If a laptop you are interested in purchasing cost $1299, what will be the amount of the discount and the final sales price after the discount is applied?

Answer 1

30% means 30/100
so basically 30% off means like
for everyone 100 dollars you get 30 dollars off, so you only pay 70

Answer 2

so like for 420 dollars you get 30% off...
let see now
for each 100 dollars u get 30 off
There are 4 hunders in 420 and 2 of 10s
as 420 = 4*100 + 2*10
so 4*(100-30) + 2(10-3)=4*70+2*7=280+14=294
notice how i knew it would be 3 dollars off the 10 since its 30 dollars off 100
same ratio off... 30%...

Answer 3
