To determine the number of ladybugs the class counted, we start by figuring out the number of ants, which is provided in the problem.
The class found 14 ants. Since each grid line on the bar graph represents 2 insects, we need to determine how many grid lines are represented by the 14 ants.
To find the number of grid lines for the ants:
- Each grid line represents 2 insects.
- Therefore, 14 insects (ants) would be represented by \( 14 \div 2 = 7 \) grid lines.
Now, the problem states that the bar for a ladybug is 3 grid lines lower than the bar for an ant. If the bar for the ants is at 7 grid lines, then the bar for the ladybugs would be:
- \( 7 - 3 = 4 \) grid lines.
Next, we convert the grid lines back to the number of ladybugs:
- Each grid line represents 2 insects, so 4 grid lines would represent \( 4 \times 2 = 8 \) ladybugs.
Therefore, the class counted 8 ladybugs.
