Easiest way to calculate 22% mark up from a cost of say 39.99

satela [25.4K]

Answer:

The markup amount on the cost 39.99 $ will be: 8.78 $

Step-by-step explanation:

Given

The cost = 39.99 (Let say in $)

Mark up = 22%

22% = 0.22

The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22

Markup amount = 0.22 × 39.99

= 8.78 $

Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $

7 2\3+ (5 1\6-1 5\9)

lorasvet [3.4K]

Start off with: 5 1/6 - 1 5/9
turn it into an entire fraction: 31/6 - 14/9
make a common denominator (which is 18): 93/18 - 28/18 = 93 - 28 = 65/18
65/18 + 7 2/3 is the new equation
7 2/3 = 23/3
23/3 = 138/18
65/18 + 138/18 = 203/18
Simplify: 203/18 = 11 5/18
Answer: 11 5/18
