If the school spent $1,137.50 and wants to make a $1500 profit, then they need to make $2637.50 to earn back what they spent and make a profit. So, if you divide $2637.50 by 350, the number of books they purchased, you get the amount each book would have to cost to make this much money. The lowest price they could sell them for is $7.54.
How long, to the nearest day, until it is safe to swim again will be 156 days
Let x represent number of day until it is safe to swim again
First step
=2000 *1/2^x
100=2000 *0.5^x
0.05=0.5^x
Second step
Log 0.05=xLog 0.5
Log 0.05/L0g 0.5=x
x=36 days* Log 0.05/L0g 0.5
x=36 days*43.22
x=156 days
Inconclusion How long, to the nearest day, until it is safe to swim again will be 156 days
