$3.00
Answer: Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
Step-by-step explanation:
1. You have the following information of Plan A:
- A 2 minute call costs .54 cents.
- A 4 minutes call costs $1.08.
2. For Plan B, you know that the cost of
is given by the equation:

3. Therefore, you can compare both plans by finding the cost of a call of 2 minutes and a call of 4 minutes of Plan B. You can calculate this by giving these values to
:

4. Substitute the values into the equation:
(This is more expensive)
(This is more expensive)
5. Therefore, Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
Answer:
It sold 43.57 iPhones for the same quarter in the previous year.
Step-by-step explanation:
It sold 61.0 million iPhone, which is an increase of 40% over the value of the previous year x.
This can be interpreted as:
61 million is 140% = 1.4 of the previous year amount, that is, x. So



It sold 43.57 iPhones for the same quarter in the previous year.
Answer: 16⅔ yds by 25 yds
Step-by-step explanation:
Let x be the length of 3 fence sections
Let y be the length of 2 fence sections
A = xy
3x + 2y = 100
y = 50 - 1.5x
A = x(50 - 1.5x) = 50x - 1.5x²
dA/dx = 50 - 3x
0 = 50 - 3x
3x = 50
x = 50/3 = 16⅔ yds
y = 50 - 1.5(16⅔) = 25 yds
