In a confined aquifer, a 50-cm diameter well fully penetrates the aquifer. The hydraulicconductivity of the aquifer was approximately 0.8 m/day. Originally, the piezometrichead was 300 m above the top of the aquifer, which is 30 m thick. If 0.8 m 3 /min ispumped from the well, what should be the depth of water in the well? What will theheight of the piezometric head be (above the top of the aquifer) at a distance of 50 cmform the well? Assume the radius of influence to be 1000 ft.

Sadie wants to sell her fan-fiction on the online platform Fanalot. Instead of selling a subscription plan to all of the stories she has written, she decides to sell readers access to each story individually. Her online research suggests that if she charges x dollars per story, she will sell 5x+100 stories per month. Fanalot will charge Sadie 20% of the amount she charges per story.
