Blueberries= $0.53
Bananas= $0.79
Apples= $0.85
Oranges= $1.46
Strawberries=$2.25
To solve this problem, we need to find two fruits that add up to $2.52.
First, let's find a fruit that costs one unit. We can go through the list and see that the cheapest fruit is blueberries, which cost $0.53.
Now, let's find a fruit that costs two units. We can subtract the cost of blueberries from $2.52 to find the remaining amount we need to spend on the second fruit. $2.52 - $0.53 = $1.99.
Next, we can search for a fruit that is close to $1.99 in price. Looking at the list, bananas are the closest, costing $0.79. But, we need to find two units. So, we multiply the cost of bananas by 2. $0.79 x 2 = $1.58.
Now, we can check if the sum of blueberries and bananas equals $2.52. $0.53 + $1.58 = $2.11. This total is less than $2.52, so we need to find another fruit that costs approximately $0.41 ($2.52 - $2.11).
Based on the list, the closest option is oranges, which cost $1.46. We need to find one unit, so we have to divide the cost of oranges by 2. $1.46 / 2 = $0.73.
Now we have two fruits:
- Vera buys blueberries for one unit since they cost $0.53.
- Vera buys bananas for two units since they cost $1.58.
Therefore, Vera buys blueberries for one unit and bananas for two units.
