11a) False. If you simplify 8/30 you get 4/15 not 2/15.
11b) False. If you simplify 6/15, you get 2/5 not 3/5.
11c) true. 5/15 can be simplified to 1/3.
First, count the difference of the cost production and the selling cost
difference = 12 - 5.8
difference = 6.2
Second, transform the difference to percentage
percentage = difference/product cost × 100%
percentage = 6.2/5.8 × 100%
percentage = (620/5.8) %
percentage = 106.9%
The mark up cost is 106.9%
Answer:
B) 38.4
Step-by-step explanation:
Answer: 2
Step-by-step explanation:
First you have to plug in the value for x which is -18 so then you're equation then get y by itself and solve for y. This becomes
-3(-18) -y = 56
54 - y = 56
-54 -54
Y=2
You can check your work by plugging in 18 for x and 2 for y and when you solve the equation your answer should equal 56.
Answer:
389.9 to 1 decimal place
