Amir has $50 to spend. She wants to buy a CD for $20 and spend the rest on jewelry sets which cost $8 each. Write an inequality
Aleksandr [31]
X = The amount of cd's
Y = Jewelry sets
X + Y = 50
X + 8y<_50
20 + 8Y<_50
Subtract 20 from both sides.
8Y<_30
Divide by 8 on both sides
Y<_3.75 (3 total)
She can buy 3 jewelry sets.

If the cost of the materials for a basic bar of soap is $2.50 and Lyndi sells each bar of soap for $4.50, what is the markup per
Nadusha1986 [10]

Answer:

80%

Step-by-step explanation:

Cost of materials for a bar of soap = $ 2.50

Selling price for a bar of soap = $ 4.50

Markup percent = \frac{selling\ price\ per\ unit - cost\ per\ unit}{cost\ per\ unit} \times 100

Markup percent = \frac{4.50-2.50}{2.50} \times 100

= \frac{2}{2.50} \times 100

= \frac{200}{250} \times 100

= 20 \times 4

= 80<em>% </em>

Step-by-step explanation:

<em>On the graphs we see transformations of exponential functions</em>

<h3>Graphic 1 = Horizontal shift </h3>
  • f(x) = 2ˣ is the parent function
  • g(x) = 2ˣ⁺³ indicates shift to the left by 3 units
  • h(x) = 2ˣ⁻¹ indicates the shift to the right by 1 unit
<h3>Graphic 2 =Vertical shift</h3>
  • p(x) = (1/3)ˣ is the parent function
  • r(x) = (1/3)ˣ⁺³ indicates shift up by 3 units
  • q(x) = (1/3)ˣ⁻² indicates the shift down by 2 units
