First we need to find the total annual costs for both the plans.
In case of leasing:
Fixed monthly cost = $420
So, yearly cost = 420 x 12 = $5040
Cost per mile = $0.08
For x miles driven, the cost per year for leasing will be = 5040 + 0.08x
In case of purchasing:
Fixed yearly cost = $4600
Cost per mile = 0.10
For x miles driven, the cost per year for leasing will be = 4600 + 0.10x
We want to find for what number of miles will the cost of leasing will be no more expensive than the cost of purchasing.
So,
Cost of leasing ≤ Cost of purchasing
5040 + 0.08x ≤ 4600 + 0.10x
440 ≤ 0.02x
22000 ≤ x
Thus, if if the number of miles driven are equal to or less than 22,000 leasing will be no more expensive than purchasing.
Answer:
1 ,5 and 3 is polynomial rest non
Answer:
The correct option is B.
Step-by-step explanation:
It is given that there is a strong, negative, linear relationship between x and y. where, x is the number of consecutive hours a worker has been assembling chainsaws and y is the number of chainsaws he can produce in an hour.
He finds that 70%of the variation in chainsaws produced per hour can be explained by the regression of y on x.
The slope is -0.7, therefore option B is correct.
Answer:
1) Brazil - 190,000,000
2) Egypt - 77,000,000
3) Australia - 20,000,000
4) Singapore - 4,400,000
5) Luxembourg - 470,000
Answer:
y = -10
Step-by-step explanation:
To solve this, you must find the value of x first. To do this you must move the first equation so that x is by itself.
-2x + 3 = 7
Subtract 3 from both sides:
-2x = 4
Divide both sides by -2:
x = -2
Now plug in -2 for x into the second equation, like so:
3x + 1 = 5 + y
3(-2) + 1 = 5 + y
-6 + 1 = 5 + y
Add like terms:
-5 = 5 + y
Subtract 5 from both sides:
-10 = y
