Complete the following chart. round dollar amounts to the nearest cent and percents to the nearest tenth of a percent.

The applicable relationships are

... markup = (markup %)/100% × cost

... cost + markup = price

The purpose of dividing by 100% is to change the markup percentage to a decimal number. Effectively, you're removing the percent sign and shifting the decimal point 2 places to the left.

In each case, fill in the numbers you know and solve for the values you don't know.

1. markup = 65.3%/100%×$120.37 = 0.653×$120.37 = $78.60

... price = $120.37 + 78.60 = $198.97

2. markup = 100%/100%×$0.43 = 1.00×$0.43 = $0.43

... price = $0.43 + 0.43 = $0.86

3. markup = (markup %)/100% × cost

You will note that (markup %) has a multiplier. Multiply the equation by the reciprocal of that. This gives you the formula for (markup %).

... markup/cost × 100% = (markup %)

... $572.59/$427.41 × 100% = (markup %)

... 1.339674 × 100% = (markup %)

... 134.0% = markup % . . . . . . . . . rounded to the nearest tenth %

... price = $427.41 + 572.59 = $1000.00

4. Same as 3.

... markup % = $10.13/$67.50 × 100% = 15.0%

... price = $67.50 + 10.13 = $77.63

5. cost + markup = price

... $19.00 + markup = $26.60

... markup = $7.60 . . . . . . . . . . . . . . . subtract $19.00

... markup % = $7.60 /$19.00 × 100% = 40.0%

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
