3. Raquel has 36 stamps. She groups the stamps into 9 equal groups. She then adds two more stamps to each group. If she gives 4 stamps to each of her 13 friends, how many stamps will she have left?

Answer:She does not have enough stamps, she is left with - 8 stamps

Step-by-step 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

2 stamps left

Step-by-step explanation:

36/9=4

4+2=6

6 stamps into 9 groups=54total stamps

2 stamps left
