Brandie is trying to decide between two cell phones. One is free with a 2-year contract, but she will have to pay the sales tax

of 8% on the original price$399 and the monthly charge is $10 more than she currently pays. The other is on sale $199 plus 8% sales tax. The monthly charge is the same as she currently pays. Over the 2-year contract period, which phone will be the lower cost and by how much?

Answer: The second plan is cheaper by $57.

For the first plan, Brandie will page $31.92 in tax, plus $10 per month of the 24 month contract of $240. The total new charge is $271.92.

For the second plan, Brandie will simply pay $214.92 (the cost of the phone including tax.

The second plan is obviously lower. Subtracting them gives us the difference.

271.92 - 214.92 = 57

Find the equation of the line passing through the point (–1, 5) and perpendicular to the line y = – 3x + 4.

Answer:

  A)  3y = x + 16

Step-by-step explanation:

The equation of a perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The constant will be chosen to match the given point.

Swapping coefficients, we get ...

  -3y = x + c

Negating the y-coefficient gives ...

  3y = x + c

Filling in the given point, we have ...

  3(5) = -1 + c

  16 = c

The equation of the perpendicular line can be written as ...

  3y = x + 16 . . . . matches choice A

_____

Note that choice A is the only equation that gives a line with positive slope. The given equation has negative slope, so its perpendicular must have positive slope.
