Answer:
c.10x90
Step-by-step explanation:
if you multiply 10 by 90 it will give you 900. i learned math a weird way. i think this only works with 10's. if you take 1 and 9 and multiply them you will get 9. then there are two zeros in total out of 10 and 90 then you add them to the 9 to get 900
$89.99 - $56.49 = $33.5
$33.5/$89.99 × 100 % = 37.22 % off
2/4= 10/20
1 4/10=14/10 14/10=28/20
10/20×28/20=7/10
I hope this helped!!!:)
