Answer:
Ms. Petno handed out 48. Ms. H handed out 57.
Step-by-step explanation:
First, because she handed out 9 more than Ms. Petno you take away that 9 from the total number of students. This will give you an even amount that they served combined. 105 - 9 = 96. Then divide by 2 to find out what they both gave out without the extra 9 she handed out. 96 / 2 = 48. Now you know that they both served 48 breakfasts without the extra 9 added on for Ms. H. Finally you add back on the 9 extra to Ms. H. 48 + 9 = 57.
This gives you with Ms. H handed out 57 breakfasts while Ms. Petno handed out 48.
57 + 48 = 105
