Answer:
B. 128 square centimeters
Step-by-step explanation:
So first make the top triangle part its own figure. By using information provided you can figure out the height of the triangle would be 3 by subtracting 11 from 14. Take 3 multiply it by the base and then 1/2 to get 18. Then find the area of the rectangle which would be 10 times 11 which is 110. Add the areas of the two parts, 110 and 18 to get 128.
23. You are expected to be familiar with the relationship
... cost + markup = selling price
a) cost + $23.99 = $119.95
... cost = $119.95 -23.99 = $95.96
b) The markup as a fraction of cost is
... markup/cost = $23.99/$95.96 = 0.25 = 25%
c) cost + markup = selling price . . . . the equation we started with
... cost/cost + markup/cost = (selling price)/cost . . . . divide by cost
... 100% + 25% = (selling price)/cost = 125%
25.
a) See part c) of problem 23. Selling price is 126% of cost.
b) Selling price = $450 × 1.26 = $567
c) Markup = $450 × 0.26 = $117
