2. Alana needs to sell 52 boxes of cookies:
She sold 7 boxes to her aunt
She sold 2 boxes to her mother
She sold 15 boxes to her neighbor
you add 7+2+15 = 24 boxes of cookies that she sold
We need to find out how many more boxes of cookies she needs to sell-
We take the 24 boxes she sold and subtract from 52 boxes that she needs to sell.
24 - 52 = 30
The answer is 30, she needs to sell 30 more boxes.

3. Sam, Jimmy and Andre shared a number of pennies in the ratio 8:5:3
Sam (8), Jimmy (5) and Andre (3)
How many more pennies did Jimmy receive than Andre?
you subtract 3 - 5 = 2
The answer is 2 more pennies.

4. Jamila spent $33.00 and Akiko spent $ 42.00
Jamila had 4 times as much money left as Akiko. How much money did each of them have in the beginning?
Since Akiko spent the highest amount- you will have to go with the higher amount to find the answer
4 x $42.00 = $168.00
They both in the beginning had $168.00
I hope this helps.
