Answer:
y = 1.20x
Step-by-step explanation
Let's call x the length of the beams in feet
Llamemps f (x) at the price of beams.
The function represented by this model is the line y = 1.20x
Where 1.20 is constant price per foot.
If the price per foot is $ 1.20, then, the price of each beam according to its size is:
6 * 1.20 = $ 7.2
8 * 1.20 = $ 9.6
10 * 1.20 = $ 12
12 * 1.20 = $ 14.4
Then we have the following points, which will constitute the domain and rank for the function:
(6, 7.2)
(8, 9.6)
(10, 12)
(12, 14.4)
Answer:
$7.20
Step-by-step explanation:
We'll need to find out 40% of 12 then subtract that amount because we're still paying 60% of the original price.
Change the percent to a decimal: 0.4
Multiply the sale price and the decimal
12 · 0.4 = 4.8
Subtract 40% of the price from 12
12 - 4.8 = 7.2
The clearance price of the checker set is $7.20
We start with the sale at $5,000. The growth is: p = 10% = 0.1; r = 1 + 0.1 = 1.1
The equation is:
f ( t ) = 5,000 * ( 1.1 )^t
where t it the time in months.
f ( 6 ) = 5,000 * ( 1.1 )^6 =
= 5,000 * 1.77156 = $8,857.80
Answer: The sale 6 months from now will be $8,857.80.
