Feme ya aeskerimi e dira dilitara di le 100 tsa aeskerimi ya tšhokolete mo diureng di le 2.  E kgona go dira dilitara di le 50 tsa aeskerimi ya vanila mo diureng di le 4.  Ke dilitara di le kae ka botlalo tse di ka dirwang mo diureng di le 48?

Colorado City uses 40% of the water from the Colorado River. If 80% of that water is used for industrial purposes, what percent of the river's total water is used by the city for non-industrial purposes?
Aeskerimi ya tšhokolete e ka dirwa ka dilitara di le 100 / diura di le 2 = <<100/2=50>>50 dilitara ka ura.
Aeskerimi ya vanila e ka dirwa ka dilitara di le 50 / diura di le 4 = <<50/4=12.5>>12.5 dilitara ka ura.
Mo diureng di le 48 go tla bo go dirilwe dilitara di le 48 * 50 = <<48*50=2400>>2400 tsa aeskerimi ya tšhokolete.
Mo diureng di le 48 go tla bo go dirilwe dilitara di le 48 * 12.5 = <<48*12.5=600>>600 tsa aeskerimi ya vanila.
Fa di kopane go tla bo go na le dilitara di le 2400 tsa tšhokolete + 600 tsa vanila = <<2400+600=3000>>3000 tsa aeskerimi.

First find the percentage of water used for non-industrial purposes: 100% - 80% = 20%
Then multiply that percentage by the percentage of water taken from the river: 20% * 40% = 8%
