Question 4

In an automated hydroponics system, the daily water delivery volume to a crop bed depends on the ambient temperature index and the pipe restriction factor.

The baseline water delivery is 8 litres. This baseline is adjusted by multiplying it by a temperature index (TTT), and then subtracting a filtration restriction constant (RRR) measured in litres.

Construct an algebraic expression to calculate the total daily water delivery volume (WWW) in litres.
