Answer:
<u>28.8%</u> of the fruit she bought on Tuesday was apples.
Step-by-step explanation:
Given:
On Monday, a fruit vendor bought 80 pieces of fruit to sell at her market, 35%, percent of which were apples and the rest of which were oranges. On Tuesday, the vendor bought the same number of oranges, but she only bought 73 pieces of fruit.
Now, to find the percentage of apples among the fruit she bought on Tuesday.
So, on Monday the fruit vendor bought 80 pieces of fruit.
35%, percent of which were apples.
So, the number of apples in the fruit are:
Thus, there are 28 apples.
Now, the rest are oranges, so we find the number of oranges by subtracting 28 apples from 80 pieces of fruit:
As, there were 52 oranges in the fruit on Monday.
And, the vendor bought same number of oranges on Tuesday.
<u><em>So, total number of fruit pieces she bought on Tuesday was 73.</em></u>
Now, to get the number of apples she bought on Tuesday we subtract number of oranges from the total number of pieces of fruit:
<u><em>Hence, the apples she bought on Tuesday was 21.</em></u>
Now, to get the percentage of fruit she bought on Tuesday was apples:
Therefore, 28.8% of the fruit she bought on Tuesday was apples.
