Th owner must buy 7 Jackets
Step-by-step explanation:
a. Purchase price=$55 , Sell Price= $77
Sell Price = $55+$22
= Purchase price + 40*55/100
=Purchase price + 40% of Purchase price
=140% of purchase price
b. Purchase Price=$35
Sell price=140%of $35
=140*$35/100
=$49
Number of Jackets required for the total sale to be $340 = $340/$49
=6.94
So We get the result by rounding off because Jackets cannot be in fraction, which is 7
Step-by-step explanation:
a:b=7:4 b:c=2:5
a:c = 7:5
900 as a fraction is 9000/10
500/1000 = 1/2 Same distance to zero and one
