The answer is the third answer because it is the only option where the number 45 is multiplied by something bigger than 1. If something is multiplied by something smaller than one then it will be smaller than the number multiplied.
Aka: 45x0.8 is 36, because 0.8 is smaller than one
A = 1 and b=2 which means 1+2 = 3
Canvas is $1 brushes are $2 and pastels are $3
I believe it should be 1.4 since the answer you get is 1.4112903226... you would round but on the tenths place 1.4
3 = AIA ( Alternate Interior Angles)
