Answer:
Polynomial Function: 3.5n + 1
Total Price of the Apples: $32.50
Step-by-step explanation:
The polynomial function is 3.5n + 1:
The 3.5n comes from the $3.50 it costs to buy an apple, and the n comes from the amount of apples bought. The 1 then comes from the tax that is added onto the price.
The total price of the apples:
3.5n + 1 ; n = 3^3 = 9
(3.5 x 9) + 1
31.5 + 1
32.5
$32.50
Answer:
The total repair cost for each store is the cost of repairs added to the sales tax. The amount of money saved will be the difference between the two total costs.
Answer: y = 3.5 x+ 43.8
Step-by-step explanation:
Here x represents the number of years after 1990
Thus, we get the table that is used to find the equation will be,
x 0 2 4 6 8
y 45 51 57 61 75
Let the equation that shows the above data,
y = b + a x ---------(1)
By the above table,
By substituting these values in the above value of a and b,
We get b = 43.8 and a = 3.5
Substitute this value in equation (1)
we get, the equation that shows the given data is,
y = 3.5 x + 43.8
⇒ Option (3) is correct.
