Question
This passage describes body coloring in stick insects.
a stick insect with stripes
A stick insect may have solid coloring or stripes on its body. Each type of coloring can help an insect blend in with a certain type of leaf.
Stick insects with solid coloring have completely green bodies. These insects blend in well with wide leaves. Stick insects with stripes have green bodies with white stripes. The stripes make the insects' bodies look like thin green strips. So, these insects blend in well with thin, needle-like leaves.
The table below describes a possible population of stick insects at the start of a period of time and at the end of that period. The table shows body coloring in the population at each point in time.
Complete the table. Write the exact answers as whole numbers or decimals.

To complete the table, we can calculate the percentages for both the start and end points in time using the following formulas:
1. Percentage with solid coloring = (Number with solid coloring / Total number of stick insects) × 100
2. Percentage with stripes = (Number with stripes / Total number of stick insects) × 100
First, let's find the total number of stick insects at the start:
- Total at start = Number with solid coloring + Number with stripes
- Total at start = 245 + 255 = 500
Now, we can find the percentages for the start:
- Percentage with solid coloring = (245 / 500) × 100 = 49%
- Percentage with stripes = (255 / 500) × 100 = 51%
Next, let's calculate the total number of stick insects at the end:
- Total at end = Number with solid coloring + Number with stripes
- Total at end = 532 + 268 = 800
Now, we can find the percentages for the end:
- Percentage with solid coloring = (532 / 800) × 100 = 66.5%
- Percentage with stripes = (268 / 800) × 100 = 33.5%
Now, we can complete the table:
| Point in time | Number with solid coloring | Number with stripes | Percentage with solid coloring | Percentage with stripes |
|---------------|----------------------------|---------------------|-------------------------------|------------------------|
| Start | 245 | 255 | 49% | 51% |
| End | 532 | 268 | 66.5% | 33.5% |
