20$ and it weighs 28 pounds
Let's convert them to decimals:
1/25 = 0.04
4% = 0.04
0.04 = 0.04
0.4 = 0.40.
So 0.4 is NOT equivalent to the other values.
X = 1 and y = 8 so (1,8) would be the correct answer
just plug in the information:
d=90
s=30
so 90=m*30^2
90=m*900
now divide both sides by 900 to get m
m=0.1
