on a purchase of $500, how much is saved by taking discounts of 20% and 10%, rather than discounts of 10% and 15%?
I'm trying to figure out what you mean by taking discounts of 20% and 10% instead of the other two.. How would you get these discounts? after each other.. the differences between the first to.. the discounts of all four?
the way i was taught was to multiply the first percentage then subtract that number from total number the multiply that number times the second percentage
multiply the first with what?
multiply the first percent 20%, for example, with 500
{80/100 * 90/100 *500} - { 90/100 *85/100 *500}
I think that depends on how exactly this question is meant.. I can see different solutions.. I'm just not sure what would work in this case.. both methods seem to be possible when the question is asked like this...
this is the correct one....!!!
can you multiply the discounts if they are substracted after each other?
no idon'tknow
here u need to find the cost after first discount then after that u again have a second discount so u will calculate the cost after second discount but this time u have to calculate the cost after doing discount on the cost which we have got after the first discount
lets here discuss the first case hope u will understand the second one by urself...!!! so cost after first discount which is of 20% u get 80/100 *500=400 and then we will calculate the price after second discount which is 10% so the cost after second discount will be 90/100*400=360
hope u understand and tell me what do u get exact answer after u solve....!!
and lso likewise u have to do in the second case...!! if u dont get just ask me...!!
thanks i understand you really are a lifesaver
ur welcome but what u get after solving i wanna make sure u get the correct anwer...!!!
also. if you want to multiply the total amount with the percentage instead of dividing first.. you have to take the fraction not the percentage... for instance 10% is equal to a fraction of 0,10 and 50% is 0,50
102.90
22.50
that is the same thing you are not subtracting that number from the original answer
right?
see u get the price after 2 discounts in the first case=360 lets here discuss the first case hope u will understand the second one by urself...!!! so cost after first discount which is of 20% u get 80/100 *500=400 and then we will calculate the price after second discount which is 10% so the cost after second discount will be 90/100*400=360
if u get it then i will tell u about the second case
i have to go now and post another problem. you guys are just awesome and if i could meet you we would be friends forever
heheeh thanx....!!!!!
