you buy 75 candy bars at a cost of $0.49 each what is the total cost of 75 candy bars? use mental math

The cost = 75 candy bars •$0.49;

75•49/100 = ((75•50) - 75) / 100 = ((75•100/2) - 75) / 100 = ((7500/2) - 75) / 100=

(3750-75) / 100 = 3675/100 = 36.75

Or

75•50cents = 37.5

considering you pay 50 cents instead of 49;

37.5 - 0.75 = 36.75

Now you took away the extra penny between 50 and 49

It took me a second but its $36.75
