jenyasd209 [6]
The first thing we need to know is how much grass the grasshopper needs to eat.
 We have:
 "must eat half its body weight in grass each day":
 (2 grams) * (1/2) = 1 gram
 Then,
 "1 blade of grass weighs 0.1grams"
 Then the amount you need to eat is given by:
 N = (1) / (0.1)
 N = 10 blades of grass
 Answer:
 
the grasshopper needs to eat 10 blades of grass each day

worty [1.4K]

Answer:

95%

Step-by-step explanation:

0.6 of 40 is 24, she bought 24 green balloons.

24 × 1.5 = 36, she bought 36 yellow balloons.

So we have

40 red

24 green

36 yellow

Then from the rest of the information, 2 red, 2 green, and 1 yellow balloon all popped.

We now have

38 red

22 green

35 yellow

for a total of:

95 balloons out of 100 original balloons, 95%
