Hello there!
So the equation I would use for this word problem is 3(s+5)=45.
3s+15=45
-15 -15
__________
3s=30
Divide 3 from both sides.
s ends up equaling 1.
Each stuffed animal elephant cost $10
3 and 60 are the extremes while 15 and 12 are the means.
306 / 3.6 = 85 gallons per minute
5,200 = 85x
x = <span>61.1764705882
hope this helps</span>
