Answer:
<em>62.5%</em>
Step-by-step explanation:
The store buys 500 shirts for $8,000.
The store bought each shirt for $8,000/250 = $32.
The markup on each shirt is $20. The percent markup is the percent that $20 is of $32. In other words, what percent is $20 out of $32?
To find what percent a part is of a whole, divide the part by the whole and multiply by 100.
percent markup = $20/$32 * 100 = 62.5%
X(x-6) = 391
x2-6x-391 =0(x-23)(x+17)=0
since the number of seats should be positive,
x = 23
The number of rows is 23 - 6 = 17
( To check our work )
391 / 17 = 23
So, there are 17 rows of seats.
If you're rounding to the nearest ten, it's 67,404.
If you're rounding to the nearest hundred, it's 67,449.
