Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for the water level, L, after d days. In how many days will the water level be 26 feet?

Sagot :

Answer:

Initial water level is 34 feet at d=0. Rate of change is -0.5 feet/day.

equation is L = 34 - 0.5d

second question:

26 = 34 - 0.5d

0.5d = 8

d = 16 days.
