Answer:
4.5
Step-by-step explanation:
8/6= 6/y
Cross multiply:
8(y) = 6(6)
8y = 36
Divide both sides by 8:
8y/8 = 36/8
y = 4.5
5 star coffee : f(x) = 8x + 40....or y = 8x + 40
custom coffee : f(x) = 12.5x + 25 or y = 12.5x + 25
the monthly fee of custom coffee, which has a monthly fee (slope) of 12.5, will have a steeper slope then the monthly fee (slope) of 5 star coffee, which has a slope of 8.
8x + 40 = 12.5x + 25
40 - 25 = 12.5x - 8x
15 = 4.5x
15/4.5 = x
3 1/3 = x.......so they would cost the same at 3 1/3 months
Therefore, custom coffee would be a better deal if u were a member for less then 3 1/3 months......and 5 star coffee would be a better deal if u were there for more then 3 1/3 months
We multiply 7 by 20 to get 140. We also multiply 7 by 2 to get 14. Add 140 to 14 to get 154
Here's how you can write it out
7 x 22 = 7 x (22)
7 x 22 = 7 x (20+2)
7 x 22 = 7x 20 + 7 x 2 ... distributive property
7 x 22 = 140 + 14
7 x 22 = 154
Answer: 154
The guarantee which should be given by the manufacturer in years is; 0.405years
<h3>Percentages and Averages</h3>
Since the average life of a scooter is 12 years with a standard deviation of 1.5 years.
Hence, the maximum life of any electric scooter is 13.5 years.
On this note, to offer a guarantee with the intention to replace only 3% of the scooters;
We must evaluate 3% of 13.5 years as follows;
- Guarantee offer = 3% of 13.5 years
- Guarantee offer = (3/100) × 13.5
Guarantee offer = 0.405 years
