Question

Of 80 t shirts 10% are white, 30% are blue and the rest are red how many are red ?

Answer 1

48 shirts are red

Explanation:

The percents have to add to 100

100 -10 -30 = 60

60% are red

80*60%

80*.6

48

Answer 2

10 % + 30 % = 40 %

100% - 40% = 60%

60% are red

Multiply total shirts by 60%

80 x 0.60 = 48

48 shirts are red
