Hello There!
Percentage increase or decrease = difference of values / original value. x 100
Percentage decrease = 80 - 76/80
80 - 76 = 4
4/80 = 0.05
0.05 x 100 = 5
In short, the decrease in Athena's daily water consumption is 5%.
Hope This Helps You!
Good Luck :)

Answer:
see explanation
Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x
