Answer:
7.75
Step-by-step explanation:
Since it is mentioned that Mia has decided to purchase 3 mangos so she incurred $1.50 × 3 = $4.5 on mangoes.
The total amount incurred is $20 and the spent amount is $4.50
So, the remaining amount left is
= $20 - $4.50
= $15.5
Now the maximum number of apples is
= $15.5 ÷ 2
= 7.75
Hence, the maximum no of apples he could purchase is 7.75
