Answer:
55% percentage mark up
Step-by-step explanation:
Formula = Gross profit / Cost of item * 100 First we find the Cost of item = 39.99 / 06 = 66.65 as 66.65 * 0.60 = 39.99 then we find the Gross profit 66.65 - 29.99 = 36.66 then plug into the formula 36.66/66.65 * 100 =55.0037509% = 55%

S would be the annual sales of the electronic device. In this case, that number is in the millions.
Therefore, our 13.9 becomes 13.9 millions.
Or written out, it would be: 13,900,000
C would be the answer. When you simplify the equations C does not contain a radical.
3.12 = 3 4/33 (<span>3.12 repeating)</span>
