In 2010, Joe bought 200 shares in the Nikon corporation for $22.07 per share. In 2016 he sold the shares for $15.11each.
slega [8]

Answer: a. $1392

b. 31.5%

Step-by-step explanation:

a. What was Joe's capital loss?

Cost price = $22.07 × 200 = $4414

Selling price = $15.11 × 200 = $3022

Capital loss = $3022 - $4414

= -$1392

b. Express Joe's capital loss as a percent, rounded to the nearest percent.

= Capital loss/Cost price × 100

= 1392/4414 × 100

= 31.5%

X - 4y = 12<br> X - 5y = 15<br> PLS HELP ME SOLVE USING ELIMINATION
balu736 [363]

Answer:

(0, -3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define systems</u>

x - 4y = 12

x - 5y = 15

<u>Step 2: Solve for </u><em><u>y</u></em>

<em>Elimination</em>

  1. Subtract 2 equations:                    y = -3

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define original equation:                    x - 4y = 12
  2. Substitute in <em>y</em>:                                     x - 4(-3) = 12
  3. Multiply:                                                x + 12 = 12
  4. Subtract 12 on both sides:                  x = 0
