Answer:
After 6 days, 3 bottles will be left.
Step-by-step explanation:
Given that:
Number of bottles = 15
Number of bottles drank each day = 2
Let,
d be the number of days
y be the number of bottles left
y = 15 - 2d
Now,
We have to find the number of days when 3 bottles will be left.
Putting y=3
3 = 15 - 2d
2d = 15 - 3
2d = 12
Dividing both sides by 2

Hence,
After 6 days, 3 bottles will be left.
-4h -6 = 22
To solve this, we need to get -4h by itself and then simplify.
-4h -6 = 22
Add 6 to both sides.
-4h = 28
Divide both sides by -4.
h = -7.

Let X = be the amount the amount that new customer will have to pay
X = 0.8P + 100
Given that the television is $1500, the discounted price is $1200. But the customer will have to pay the membership of $100.
Therefore the total amount is $1300.
The total calories burnt in 20 minutes are 200
Step-by-step explanation:
We have to do simple multiplication to find the number of calories burnt.
Given
Number of calories burnt in one minute = c = 10
Time = t = 20 min
So the total number of calories burnt in 20 minutes will be:

Hence,
The total calories burnt in 20 minutes are 200
