Gaming systems are on sale for 20% off the original price (g), which can be expressed with the function p(g) = 0.8g. Local taxes are an additional 12% of the discounted price (p), which can be expressed with the function c(p) = 1.12p. Using this information, which of the following represents the final price of a gaming system with the discount and taxes applied?
c(p) + p(g) = 1.92g
c[p(g)] = 0.896g
g[c(p)] = 1.92p
c(p) ⋅ p(g) = 0.896pg

Best ResponseYou've already chosen the best response.1p(g) gives you the discounted price. You need to apply function p first. Then c(p) gives you the final price after the tax is added to the discounted price. You apply function c after function p.

Best ResponseYou've already chosen the best response.0start with the original price and take the 20% off . this is now the "x" to use to figure the taxes

Best ResponseYou've already chosen the best response.1That means you need: c(p(g))

Best ResponseYou've already chosen the best response.1First, let's write c(p) dw:1437507064770:dw

Best ResponseYou've already chosen the best response.1Now to find c(p(g)), you replace p(g) by what the function p(g) is equal to. dw:1437507122077:dw

Best ResponseYou've already chosen the best response.1Now just multiply out 1.12 * 0.8 to simplify c(p(g))

Best ResponseYou've already chosen the best response.1That means if you take each original price and just multiply it by 0.896, you are discounting the price by 20% and adding a 12% tax. With one simple multiplication, you are discounting and adding tax. For example if a system had an original price of $100, the final price after the discount and tax is 0.896 * $100 = $89.60
