Jamie purchased a DVD that was on sale for 15% off. The sales tax in her county is 5%. Let y represent the original price of the
damaskus [11]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Sale off = 15%

Rate of sales tax = 5%

Let y be the original price of the DVD.

Amount of sales tax would be

\dfrac{5}{100}\times y\\\\=0.05y

Amount after tax would be

y + 0.05 y = 1.05y

Now, there is off of 15%, so final cost of the DVD would be

\dfrac{100-15}{100}\times 1.05y\\\\=\dfrac{85}{100}\times 1.05y\\\\=0.85(1.05y)

Hence, Option 'D' is correct.

Solve the system by substitution. Check your solution.
postnew [5]

Answer:

(9,126)

Step-by-step explanation:

Make sure x and y are on the same side

0.5x+0.25y=36\\16x-1y=18

Eliminate y by multiplying the first equation by 4 then adding both equations together

2x+1y=144\\16x-1y=18\\18x=162\\x=9

Plug the x value (9) into one of the equations

16(9)-1y=18

Solve

16(9)-1y=18\\144-1y=18\\144=18+1y\\126=y

x=9, y=126

(9,126)
