The amount of tax for each camera is $5.25 and the tax rate is 6%. explain how the equation: (original cost)(percent) = tax amount is adjusted to solve for the original cost.

x(1.06)=5.25

The reason it is 1.06 is because it is the original cost plus tax. You can divide each side by 1.06 to get x roughly equals 4.95.

So $4.95 is roughly what the camera costs rounded to the nearest cent.

The equation is adjusted by dividing the tax amount by the percent to find the original cost. Dividing by the percent is the inverse operation of multiplying by percent.

Sample Response

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
