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.

If 32.16 includes the sales tax....then the price before the sales tax will be less then 32.16
that only leaves 2 choices.....
so lets check them...
7% sales tax on 2.25 = 0.07(2.25) = 0.16....so if u spent 2.25 on groceries and added the sales tax of 16 cents....then u would have spent 2.41...thats a long way from 32.16
if u spent 30.06...with 7% sales tax....u would spend 30.06 + 0.07(30.06) = 32.16
so the cost of the groceries before the sales tax is 30.06 <==
