Answer:

The tax would be $0.95, and the total would be $18.20.

Step-by-step explanation:

From what we know, the calculator costs $17.25 and the tax rate is 5.50%, which is the same as 0.055 times the original price. Knowing this, multiply 17.25 (69/4) by 1.055 (211/200).

69/4 * 211/200

<em>EX Step: I'll make this a single fraction for convenience.</em>

(69 * 211)/(4 * 200)

<em>Step 1a: Multiply 69 by 211 to get 14,559.</em>

14,559/(4 * 200)

<em>Step 1b: Multiply 4 by 200 to get 800.</em>

14,559/800

<em>Step 2: Divide 14,559 by 800 to get 18.19875.</em>

18.19875

<em>Step 3: Round to the nearest cent.</em>

The total cost of the calculator is $18.20.

<em>Step 4: To find the tax, subtract the total price (w/ tax) from the original price.</em>

$18.20 - $17.25

<em>Tip: You can subtract the two decimal values (.20 and .25) from each other. If the result is positive, add that to 0. If negative, subtract from 100.</em>

20 - 25 = -5 (subtract from 100)

100 - 5 = 95 (This is the decimal portion, the whole is 0.)

The tax is $0.95.

Step-by-step explanation:

A system of two equations can be classified as follows:

1) If the slopes are the same but the y-intercepts are different, the system has no solution.

<em>2) If the slopes are different, the system has one solution.</em>

3) If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions
