Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.
Teacher c makes the most money at the end of their career since the model is entirely linear.
Wesley will need 10 10-inch stones, and 9 5-inch stones.
Since he wants to begin and end the pattern with 10-inch stones, we put a 10 at the beginning and end.
10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10
10 x 10-inch = 100 inches
9 x 5-inch = 45 inches
100 + 45 = 145 inches
