YOU ARE COOL!!!
Step-by-step explanation:
PLS RATE THE QUESTION GOOD I TRY TO GET POINTS❤️❤️❤️❤️
Since 3 neckties will be out from the
store, so you need to know how much is the cost of 3 ties.
$59.99 x 3 = $179.97 and divide it by two
because the costumer will only pay for 2
$179.97 / 2 = $89.99 is the new price
Mark up = 89.99 – 59.99 = $30.00
% mark up = [(89.99/59.99) -1] * 100
= 50%

Here, Let the number of weeks = x
Then, Equation would be: 850x - 300x - 7500 = 0
550x = 7500
x = 7500 / 550
x = 13.63
Minimum week can't be in decimal, so we have to pick for nearest larger value which is 14.
In short, Your Answer would be: 14 Weeks
Hope this helps!
