Discount of 40% or Discount of 20% followed by 22%.

Let's use $100 as an example.

Discount of 40%:

$100 * 40% <-- 40% is equal to 40/100 or 0.40

$100 * .40

$40 Savings

Discount of 20% followed by 22%:

$100 * 20% <-- 20% is equal to 20/100 or 0.20

$100 * .20

$20 Savings

$100 - $20

$80 Remaining price, take 22% off

$80 * 22% <-- 22% is equal to 22/100 or 0.22

$80 * 0.22

$17.60 Savings

$20 First Discount Saving + $17.60 Second Discount Saving

$37.60 Total Savings

The 40% discount is better.

The 40% discount is better because you are taking 40% off a larger number. Although the sum of 20% and 22% are greater; the 22% is taken off the smaller number which reduces the actual dollar you save. You would have needed to take an additional 25% off for the second discount to equal the value of the 40% used in this scenario.

a discount of 40%. Lets say you bought something for $100. a 40% discount would drop it donw to $60. now lets say you bought the same thing with a 20% discount. that drops it down to $80. Now you take 22% off of $80. 22% of $80 is $17.60. So 80 - 17.60 is $62.40. Thats $2.40 more you have to spend than straight 40%

The assignments will be emailed to the figure(s) or the instructor can print the abode artwork task on a sheet of paper and make copies for each pupil or the father and mom can get admission to the homework through the college's website. expecting 7 365 days olds to jot down homework assigments is rather hopeful, yet not very sensible.
