Determining the Final Cost of an Item The tax rate as a percent, r, charged on an item can be determined using the formula-1 =r, where c is the final
cost of the item and p is the price of the item before tax. Louise rewrites the equation to solve for the final cost of the
item: c=p(1 + r). What is the final cost of a $40 item after an 8% tax is applied?

Which inequality has a dashed boundary line when graphed ?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
