Aleonysh [2.5K]

Answer: D) 10 jerseys

Step-by-step explanation:

Let j represent the number of jerseys and C for total cost

Local company eqn: C = 5.25j + 45

Online company eqn: C = 7.75j + 20

Set both sides equal to solve:

5.25j + 45 = 7.75j + 20

5.25j - 7.75j = 20 -45

- 2.5j = -25

\frac{-2.5j}{-2.5}=\frac{-25}{-2.5}

j = 10

Therefore, the cost is the same for both companies when 10 jerseys are sold

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

Step-by-step explanation:

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

x/a + b = c

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

  1. Subtract <em>b</em> on both sides:                    x/a = c - b
  2. Multiply <em>a</em> on both sides:                     x = a(c - b)

You make $25000 a year, and you get a 10% raise. Your new salary is $____ The next year you get a 10% cut. Your new salary is $_
gtnhenbr [62]

Firstly, we have to find out what 10% of $25000 is. To do this, multiply $25000 by 0.1 (10% in decimal form): \$25000 \times 0.1=\$2500 . <em>$2500 is the 10% raise.</em>

Next, to find your first new salary, add $25000 and $2500 together: \$25000+\$2500=\$27500 . <u>$27500 is your new salary after the 10% raise.</u>

Next, we need to find 10% of $27500. It's a similar process as to finding 10% of $25000. \$27500 \times 0.1=\$2750 . <em>$2750 is your 10% cut.</em>

Next, since this is a cut, subtract $2750 from $27500. \$27500-\$2750=\$24750 . <u>$24750 is your new salary after the 10% cut.</u>

Next, to find the percentage change, firstly divide $24750 by $25000. \frac{\$24750}{\$25000}=0.99\ \textsf{or}\ 99\% . Now this shows that your current salary is 99% of what you used to make. It is <em>not</em> how much less you make. To find how much less it is, subtract 99% from 100%: 100\%-99\%=1\% . <u>Your current salary is 1% less than what you used to make.</u>
