A family swimming pool holds 60m2 of water. The function below gives the cubic
meters of water in the pool, taking into account water lost to evaporation over x
days. How much water does the pool have after 7 days?
f(0) = 60 - 0.187

Since, we want to figure out how much water (from 60 m^3) is remaining after 7 days, we simply have to plug in x = 7 into the function. Whatever number we get, is the AMOUNT OF WATER REMAINING AFTER 7 DAYS.

So,

[tex]f(x)=60-0.18x\\f(7)=60-0.18(7)\\=58.74[/tex]

Thus, the amount of water remaining in the pool after 7 days is 58.74 cubic meters
