Answer:
3 ; $11.97
Explanation:
Given that:
Balloon options : 15 and 12
Every bouquet has same number of each color :
Greatest possible number of bouquet possible using all the balloons :
Greatest common factor of both 15 and 12:
15 : 1, 3, 5, 15
12 : 1, 2, 3, 4, 6, 12
Hence the greatest common factor of both 15 and 12 is 3
Hence,
Greatest possible number of bouquet possible using all the balloons = 3
If each bouquet is sold for $3.99 :
Earning will be :
Number of bouquet * price per bouquet
3 × $3.99
= $11.97
