Answer:

This shows that a system of equations may have one solution (a specific x,y-point), no solution at all,

explanation: solution (being all the solutions to the equation). You will never have a system with two or three solutions; it will always be one, none, or infinitely-many.

A CD usually sells for $15.00. If the CD is 10% off, and sales tax is 5%, what is the total price of the CD, including tax?
dybincka [34]

Answer:

<em>The total price of the CD is $14.18</em>

Step-by-step explanation:

<u>Percentages </u>

We can compute additive or subtractive percentages by using these formulas. If we have a number X and want to increase it by Y%, then the increase is xY/100. Thus the new value for the number is x+xY/100 or equivalently

X(1+Y/100)

If we want to decrease by Z%, the new value is

X(1-Z/100)

The regular price for a CD is X=$15. The CD is Z=10% off, so the sale price is

15(1-10/100)=\$13.5

But we have to add the tax of Y=5%, so the final value is

13.5(1+5/100)=\$14.18

The total price of the CD is $14.18

The snowboard Hannah wanted originally cost $109.It had been marked down 10% and then another 12%. A tax of 6% was added to the
lara [203]

Take 10% of the snowboard price.

10% = 0.1

109 * 0.1 = $10.90 (10% discount)

109 - 10.9 = $98.10 (Price with discount).

Take 12% of the new snowboard price.

12% = 0.12

98.1 * 0.12 = 11.772 (Round to 11.77)

98.10 - 11.77 = $86.33 (Final discounted price)

Take 6% tax on the new snowboard price.

6% = 0.06

86.33 * 0.06 = 5.1798 (Round to 5.18)

86.33 + 5.18 = $91.51

______

After solving Hannah doesn't have enough money to buy the snowboard.

______
