The answer is A
your expression said 5×20=100 +3×20=60 So 100+60=160
now the option A is5+3=8 then 8×20=160 there the same product

Yea that’s a nice graph i’d say looks a little fishy though
3-83= 80
80 divided by 2 is 40
the answer is 40
2300 cups because if 460 is 20%, multiply the 460 x 5 to get 100%
