James spent $20.16 on comic books. Each comic book cost $0.72. After he read the comic books, James sold each one for $0.20 less
adell [148]

Answer:

$14.56

Step-by-step explanation:

<u><em>Steps to answering this question </em></u>

  1. Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic
  2. Determine the selling price of the comic
  3. multiply the amount of comics bought by the selling price

the total number of comics bought = total amount spent on comics / per unit price of comics

$20.16 / $0.72 = 28

selling price = 0.72 - $0.20 = $0.52

Total amount received = selling price x total comics bought

$0.52 x 28 = $14.56

Y = 3/2x + 15, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.
Ray Of Light [21]

Answer:

The y-intercept is 15, which means the ordered pair is (0, 15), and the x-intercept is -10, which means the ordered pair is (-10, 0)

Step-by-step explanation:

To find the y-intercept it is quite easy. Since this is written in slope-intercept form, we can see the y intercept as the constant at the end of the equation.

The x-intercept can be found by inputting 0 for y and then solving for x.

y = 3/2x + 15

0 = 3/2x + 15

-15 = 3/2x

-10 = x
