A trip, including hotel and air, is prices at $319.19 after tax. If the tax rate is 12%, calculate the price before tax that wil

Crank

Answer: $285

Step-by-step explanation:

Given

A trip costs $\$319.19$ after-tax inclusion

The rate of tax is 12%

Suppose x is the amount of charge before tax inclusion

We can write

$\Rightarrow x+12\%x=319.19\\\Rightarrow x(1+0.12)=319.19\\\\\Rightarrow x=\dfrac{319.19}{1.12}\\\\\Rightarrow x=\$284.99\approx \$285$

The amount before tax inclusion is $285

Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim.

Brrunno [24]

Answer:

Domain and range are the set of all real numbers.

Step-by-step explanation:

Given that Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim

Here no restriction is mentioned for the number N.

It can be any number but real.

Hence we can say that domain is the set of all real numbers

For range let us calculate y for any x

If Ann thought of x as the number then

she would multiply by 5 to get 5x and add 7 to get 5x+7

Hence y =5x+7

Since y has no exception here range can also be the set of all real numbers
