A department store buys 400 shirts at cost of $7,200 and sells them at a selling price of $20 each. Find the percent markup.
The percent markup is %. (Round to the nearest whole number as needed.)

Find the required measurements of the following trapezoids. a = 8 cm b = 16 cm h = 10 cm

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
