A book costs $12.50 plus sales tax. After tax it costs $13.25. What is the sales tax rate?
WINSTONCH [101]

Answer:

The rate of sales tax is 6%.

Step-by-step explanation:

First you must subtract 12.50 from 13.25

This brings you to .75

Then, divide .75/12.50 to get 0.06 which is equivalent to 6 percent.

Iteru [2.4K]

Option A: 6x^2+75x+200 is the correct answer

Step-by-step explanation:

The profit is obtained by subtracting the cost from the revenue.

Given

R(x) = 6x^2+100x+300\\C(x) = 25x+100

The Profit function will be obtained by subtracting the cost function from the revenue function

So,

P(x) = R(x) - C(x)\\= (6x^2+100x+300)-(25x+100)\\=6x^2+100x+300-25x-100\\=6x^2+100x-25x+300-100\\P(x)=6x^2+75x+200

Hence,

Option A: 6x^2+75x+200 is the correct answer
