1 liters y and 1 liters b since the question states that you need to add
Answer:
1 
more cups of flour
Step-by-step explanation:
A.) 200+15m=395. This is because the initial price is 200, and after that she will add $15/month. The equation you chose would be exponential, meaning the rate would increase as time passed, which is not the case. Instead, the rate is constant, and the only think that changes is m, the number of months.
b.) I believe it will be easier to answer with ^this equation.
c.) The rate of change would be 15, since the rate is increasing monthly by $15.
d.) Once you solve 209+15m=495, you'll have the answer.
XLVIII or 48.3. Im not sure if its right and you may want to double check with other answers.
The sum of two supplementary angles is 180 degrees.
A+B=180.
80+B=180
B= 180-80
B=100
