Joanne works for a florist. She needs to estimate how many flowers to order for 12 wedding bouqeets. She did similiar bouqets for two weddings in the past. For on she used 72 roses for 5 similar bouets and for the other, she made 16 similar bouqets using 243.
How many flowers should Joanna estimate she needs for this wedding?
[show work, please.]
How many flowers should Joanna estimate she needs for this wedding?
The numbers don't quite match, but let's use hte higher ratio to be safe.
243/16 roses per bouquet means 12 bouquets will require
12*243/16 = 183 roses
Reply:Well in the first one she used (72/5) 14.4 roses in each bouquet. in the second wedding she used (243/16) 15.18 roses per bouquet. I would average the 2 previous weddings together (14.4+15.18)/2 to get 14.79 roses.
12 wedding bouquets at 14.79 roses (12x14.79)=177.48,178 roses.
Reply:(243-72)/(16-5) = 15.5
y = 15,5x +b
72= 15.5(5) +B --%26gt; b = -5.5
y = 15.5x- 5.5
y(12) = 15.5*12 -7.5 = 181
