Retail prices in a department store are obtained by marking up the wholesale price by 20%. That is, retail price is obtained by adding 20% of the wholesale price to the wholesale price. (A) What is the retail price of a suit if the wholesale price is $300? (B) What is the wholesale price of a pair of jeans if the reta ns if the retail price is $48? (A) What is the retail price of a suit if the wholesale price is $300? The retail price is $. A farmer buys a new tractor for $157,000 and assumes that it will have a trade-in value of $87,000 after 10 years. The farmer uses a constant rate of depreciation to determine the annual value of the tractor. (A) Find a linear model for the depreciated value V of the tractor t years after it was purchased. V= (Type your answer in slope-intercept form.) The Consumer Price Index (CPI) is a measure of the average change in price over time from a designated Year CPI reference period, at wh 1960 29.6 based on prices of basic consumer goods and services 1973 44.4 The table provided lists the CPI for several years from 1960 to 2012. If the price change in cars parallels the 1986 109 .6 change in the CPI, what would a car sell for (to the 1999 156.9 nearest dollar) in 2012 if a comparable model sold for 2012 229 .6 $12,500 in 1999? In 2012, a car would sell for approximately $]. Round to the nearest dollar.) (A) Find the slope of the line that passes through the given points. (B) Find the standard form of the equation of the line. lope-intercept form of the equation of the line (-4, -1) and (1, - 7 (A) Find the slope of the line that passes through the given points. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. m= (Type an integer or a simplified fraction.) O B. The slope is not defined A publisher for a promising new novel figures fixed costs (overhead, advances, promotion, copy editing, typesetting, and so on) at $63,000, and variable costs (printing, paper, binding, shipping) at $2.70 for each book produced. With his pricing, 3866 books need to be produced and sold at $19.00 each for the publisher to break even. However, rising prices for paper require an increase in variable costs to $3.20 for each book produced. Use this information to complete parts a. through c. . What strategies might the company use to deal with this increase in costs? Choose all that are reasonable. A. Increase the selling price of the book. B. Increase the font size of the print in the book. C. Decrease the fixed costs D. Find different suppliers to try and lower the variable costs Graph the following equation. 6x - 3y = 6 Use the graphing tool to graph the equation.

Assume the relationship between the cost y to produce x cups of coffee is linear. a. Write a linear equation that expresses the cost, y, in terms of the number of cups of coffee, x. b. How many cups of coffee are produced if the cost of production is $249.00? a. y=(Use integers or decimals for any numbers in the expression.) Use the graph of the line to find the x-intercept, y-intercept, and slope. Write the slope-intercept form of the equation of the line. Q The x-intercept is Type an integer or a simplified fraction.)
