Final answer:
The total amount of money being taken into the store is $90.
Step-by-step explanation:
To find out how much money is being taken into the store, we need to calculate the total amount of money each student has and add them up.
There are 3 boys, and each boy has $5, so the total amount of money the boys have is 3 * $5 = $15.
There are 6 girls, and half of them have $5 more than the boys, while the other half has $10 more than the girls with $5 more.
This means that half of the girls have $5 + $5 = $10, and the other half have $10 + $5 = $15.
So, the total amount of money the girls have is (6/2) * ($10 + $15) = 3 * $25 = $75.
The total amount of money being taken into the store is $15 (from the boys) + $75 (from the girls) = $90.
