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:
One solution
Step-by-step explanation:
Hi,
3(x + 5) = -4x + 8
3x + 15 = -4x + 8
7x + 15 = 8
7x = -7
x = -1
One solution :)
Answer:
3
Step-by-step explanation:
from the question,you get an expresion of
6n-5= n + 10
5n = 15
Isolate n
5n/5 = 15/5
n+3
To make it like a simple, I'll make an equation. Let x be the number of hours because x represents unknown and we don't know the hours. Then your per hour is $7.25 right? so it would be x7.25. You want to know how many hours you will work so you can earn $125. The equation is simple as this x7.25 = 125.
All you have to do is divide the equation by 7.25 because that's your per hour.
It will look like this, <u>x7.25</u> = <u>125</u> then the answer would be 17.24 hours.
7.25 7.25
