let's say the shirt has the list price of $100 if you take 25% off, what is the shirt price now?

OpenStudy (vbcvbcbcvbvc):

75

jimthompson5910 (jim_thompson5910):

if we have a list price of $100 and we take 80% of that, we get 0.8*100 = 80 agreed?

OpenStudy (vbcvbcbcvbvc):

yes

jimthompson5910 (jim_thompson5910):

now let's take 5% off that 80 - (5% of 80) = 80 - 0.05*80 = 80 - 4 = 76

jimthompson5910 (jim_thompson5910):

so if we buy online, then we pay $75 for the shirt if we buy in store, and we're a member, then we pay $76 for the shirt the online option is better because we save $1

jimthompson5910 (jim_thompson5910):

take the amount you save ($1) and divide it by the original list price 1/100 = 0.01 = 1% so the answer is 1.00%

OpenStudy (vbcvbcbcvbvc):

oh ok thx

no problem
