The number of minutes that would make the water level be less than or equal to 64 cups is;
160 minutes.
We are given the equation;
W = -0.414t + 129.549
where;
t is the number of minutes
W is the level of water
The expression to find the amount of time it will take for the water level be less than or equal to 64 cups is;
-0.414t + 129.549 ≤ 64
Using substitution property of equality, subtract 129.549 from both sides to get;
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549
Using division property of equality, divide both sides by -0.414 to get;
t ≤ -65.549/-0.414
t ≥ 158.33
(sign changed to ≥ because we divided the inequality by a negative number.)
We have to approximate the inequality to get;
t = 160 minutes.
