Melissa is buying a sweater. The original cost of the sweater is $18.00. The sweater is 15% off, and the sales tax is 8%. How much will the sweater cost?

$14.07

Step-by-step explanation:

100-15=85

You change this into a multiplier 0.85.

18x0.85=15.30

100-8=0.92

0.92x15.30=14.07

Hope this helps you

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
