Answer:
8 flowers in each bunch
Step-by-step explanation:
From this information, we can make the equation:
Where 
is the number of flower in each bunch.
<em>Add 46 to both sides</em>
<em>Divide both sides by 23</em>
There are 8 flowers in each bunch.
Number of apples purchased = A
Cost of each apple = 15 cents
Then
The total cost of 15 apples = 15A
Number of bananas purchased = B
Cost of each banana = 10 cents
Then
Cost of 10 bananas = 10B
So
The total value of purchase = 15A + 10B
So the correct option among all the options given in the question is option "D",. I hope the procedure is clear enough for you to understand. Using this procedure it will be possible for you to answer similar questions with ease and without requiring any help from outside.
