Answer :
Combining the number of balloons, it is found that she bought 440 balloons.
------------
- She bough 40 red balloons.
- The number of green balloons is 5/2 the number of red balloons, thus:
[tex]\frac{5}{2} \times 40 = \frac{5 \times 40}{2} = \frac{200}{2} = 100[/tex]
100 green balloons.
- The number of green balloons is 1/3 of the number of yellow balloons, thus the number of yellow balloons is the triple of the number of green balloons, thus she bought 3(100) = 300 yellow balloons.
- Combining all, in total, she bought 40 + 100 + 300 = 440 balloons.
