Answer:She does not have enough stamps, she is left with -8 stamps
Explanation:
Okay so we have 36 stamps into 9 equal groups. So let's divide 36/9=4
two stamps are given to each group so we have 2x4=8+36=44. Now we need to find out how many stamps are given away in total with 4x13=52 and now we subtract 44-52=-8. She does not have enough stamps.
This formula can be simplified to ((36/9)+(2x4))-(4x13)=-8
