25×(1−0.18)^(4)
=11.30
25*0.01=25(1-0.18)^t
0.25=25(0.82)^t
0.25/25=(0.82)^t
t=log(0.25/25)/log(0.82)
t=log(0.25÷25)÷log(0.82)
t=23.21 hours
(14+19+x)/3=17
x= 18
the first is the equation and the second it the answer

Y is 85% of 60
Equation: Y = P% * X
Solving our equation for Y

Y = 0.85 * 60
Y = 51
