Answer:
x=-4
Step-by-step explanation:
Divide both sides by 1/4
(x+12)=2 (2 divided by 1/4 =8)
(x+12)=8
Subtract 12 from both sides
x=-4 (parenthesis disappears after 12 is subtracted)
Mary needs to sell 180 bubble teas to earn $216
Answer:
P = 867(1.07)^t
Step-by-step explanation:
The population of muskrats oscillates 33 above and below average during the year, hitting the lowest value in january.
If the average value = 900 muskrats
Then the lowest = 900 - 33 = 867
It increases by 7 % each month
R = 7%
equation for the population p in terms of the months since january t will be
P = Po( 1 + R%)^t
P = 867( 1 + 0.07) ^t
P = 867(1.07)^t
