at earthy eatery restaurant, 80% of the 40 menu items are vegetarian. how many menu items are vegetarian?
pick the model that represents the problem.
two bar models with percentages and numbers
how many menu items are vegetarian?
blank menu items

Explanation:

Step1: Understand the problem

We need to find 80% of 40 menu items. The formula for finding a percentage of a number is $Percentage\times Total = Part$. Here, the percentage is 80% (or 0.8 in decimal), and the total number of menu items is 40.

Step2: Calculate the number of vegetarian items

First, convert 80% to a decimal: $80\% = \frac{80}{100} = 0.8$. Then multiply this by the total number of menu items (40): $0.8\times40 = 32$.

For the model part, the first model (the blue one) has the total as 40 (at 100%) and we are looking for the value at 80%, which matches our problem (finding 80% of 40). The second model has 40 at 80% and is looking for the total, which is not our problem. So the first (blue) model represents the problem.

Answer:

The model that represents the problem is the first (blue) bar model. The number of vegetarian menu items is 32.
