Answer:
350 Stamps left
Step-by-step explanation:
First do 5/8*400= 250
Then take 1/5 of it 1/5*250
You end up with 50 so do 250-50= 200 and add the 150 Canadian stamps to get a total of 350 stamps.
C = 1.39 + 0.5(n - 1), where C is the cost and n is the number of days
C = 1.39 + 0.5(6)
C = $4.39
Answer:
B
Step-by-step explanation:
We have

Here the value of a is always positive because distance is positive

Next, we factor out 7 to get our period

So our period is

Next, our phase shift we set the inner parenthesis equal to 0.


So our phase shift is -3/7
A)1. 60/6=10
2. 56/7=8
3. 10-8=2
B)1.10
2.8
3.10+8=18
C)1. 360
2.392
3. 360+392=752
D)1. 360
2. 392
3. 360-392=-32
