Answer:
45 mugs
Step-by-step explanation:
she already has sold 116 mugs and 50% would be 161 soooo 161-116=45 more mugs
Since the denominator cannot be zero, you can set 4z+1=0 to find the excluded values.
4z+1=0
4z=-1
z=-1/4
And thus, z cannot equal -1/4
The answer is either x = -1 or x = 4.
(To any other people, please correct me if I'm wrong) I believe that the answer would be at the rate of 24.4 miles per gallon
