Since the jar is 12 ounces, we want to find the price when it is one ounce. We do this by dividing the price, $3.60, by 12:

3.60/12 = 0.3

So, the answer is $0.30/oz, or (B).

A store owner bought a painting for $120. She is selling it for $190. What is the percent markup on the painting
stiks02 [169]

Answer:

The markup percent on the painting is 58.3%

Step-by-step explanation:

Here, The Cost price of the painting = $120

The selling price of the painting = $190

Hence, the total profit on the painting = Cost Price - Selling price

or Profit =  $190  - $120 = $70

Now, Markup % =  (Gross Profit / cost)  x 100

⇒Markup % = \frac{70}{120}  \times 100 = 58.3

Hence, the markup percent on the painting is 58.3%

I need help with number 7 and 8
devlian [24]
7.

The point-slope form of the equation of a line is

y - y1 = m(x - x1)

where m is the slope, and (x1, y1) is a point on the line.

We are given two points, so we can find the slope.

slope = m = (y2 - y1)/(x2 - x1)

The slope of this line is

m = (-3 - 7)/(5 - (-15)) = -10/20 = -1/2

Since every choice has a 7 and a 15, we now use point (-15, 7) and slope -1/2.

y - y1 = m(x - x1)

y - 7 = -1/2(x - (-15))

y - 7 = -1/2(x + 15)
