Some landscapers just finished planting a new flower garden. They used pink, yellow, and blue flowers. For every 6 pink flowers, There are 5 yellow flowers and 7 blue flowers. There are 450 flowers altogether. How many of the flowers are yellow?

AAAaannndd the bot gets it wrong yet again!

6x+5x+7x = 450
x = 25
pink:yellow:blue = 6:5:7 = 150:125:175
so there are 125 yellow
