Assume the following cost of goods sold data for a company: 2016 $1,704,000 2015 1,400,000 2014 1,200,000 If 2014 is the base year, what is the percentage increase in cost of goods sold from 2014 to 2016? a. 70.4% b. 42% c. 85.7% d. 117%

b. 42%

Explanation:

The percentage increase in cost of goods sold from 2014 to 2016 is ratio of the difference between the cost of sale in both years to the cost of sales in 2014 expressed as a percentage.

Mathematically,

percentage increase in cost of goods sold from 2014 to 2016

= (b - a)/a *100%

where a =  2014 cost of sales, b = 2016 cost of sales

percentage increase in cost of goods sold from 2014 to 2016

= ($1,704,000 - $1,200,000)/$1,200,000

= 0.42

= 42%

i think this is true i hope this

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
