The difference in the price per bag for 150 bags versus 50 bags is $0.05 per bag
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more variables and numbers.
From the diagram:
Price for 150 bag = $38
Cost per bag = $40 / 150 = $0.25
Also:
Price for 50 bag = $15
Cost per bag = $15 / 50 = $0.30
Difference in price = $0.30 - $0.25 = $0.05
The difference in the price per bag for 150 bags versus 50 bags is $0.05 per bag

Answer:
First Place wins in 15 events
Second Place wins in 12 events
Step-by-step explanation:
Let
the number of events winning first place be "f"
the number of events winning second place be "s"
Total 27 swimming events, we can write:
First place wins is THREE MORE than 2nd place wins, so we can write:
Replacing 2nd equation in 1st equation, we can solve for "s":
We know
f = s + 3
so,
f = 12 + 3
f = 15
Thus,
<u>First Place wins in 15 events</u>
<u>Second Place wins in 12 events</u>
