George sells widgets. the first 10 widgets a customer purchases cost x dollars each. every widget purchased after 10, each cost 50% of x. if ron spent $21.00 on 11 of george's widgets, what is the value of x?

  2

Step-by-step explanation:

The cost for 11 widgets is ...

  10x + (11 -10)(0.5x) = 21.00

  10.5x = 21.00 . . . . . . . . . . . . collect terms

  21.00/10.5 = x = 2 . . . . . . . . divide by the coefficient of x

The value of x is 2.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
