53% of 470 is exactly 249.10000000000002. What ever is closest to that is your answer.
In 24 hours, the worm climbs 5 feet.
7-2= 5 (the worm falls 2 feet every night)
So,
5*8=40
It will take bruce's worm about 8 days to get to the top of the well.
I hope this helps!

16 +28+32+4=80 80 total coins x.15 =12 coins sold
the answer would be 8 because using pemdas
1*10=10
10-10/5
10/5=2
10-2=8
Hypotenuse^2=12^2+5^2=144+25=169
⇒ hypotenuse =V169=13 cm
