You would need 14 cases. You multiply 150 times 2 to get 300 which is 2 cases of soap per day and you multiply 7 days in a week by 2 and you let math magic happen
C is the answer you are looking for.
Answer:
x = 7
y = -7/2
Step-by-step explanation:
(x+6i)=(3-i)+(4-2yi)
First look at the real parts
x = 3 +4
x = 7
Then look at the imaginary part
6i= -i -2yi
6 = -1-2y
Add 1 to each side
6+1 = -2y
7 = -2y
Divide by -2
7/-2 = y
