The water level is receding in the cape fear river at a rate of 25ft per day. the water level is at 45ft. (a) write an equation (b) what is the height of the river after 10 days

Step-by-step explanation:

A)

We know that the water level is decreasing by 25 ft per day. This means that -25x would be the first part of the equation.

We also know that the water level starts at 45 ft when x=0.

Given this information, we can create an equation as follows

B)

Now that we have our equation, we can plug in 10 for x in order to find the height of the river

This means that after 10 days, the height of the river is -205 ft.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
