You and a friend want to start a business and design t-shirts. you decide to sell your shirts for $15 each and you paid $6.50 a piece plus a $50 set-up fee and $25 for shipping. how many shirts do you have to sell to break even? round to the nearest whole number.

you're selling the t-shirts at $15 a pop, so if you sell say Q quantity of shirts, your Revenue is 15Q.

your costs are a one-time setup fee of 50 bucks plus 25 bucks for shipping, so 75 bucks fixed cost, and you paid $6.50 to make each t-shirt, so if you make Q quantity of shirts, your costs will then be the 75 bucks plus 6.5Q.

the break-even point is where the revenue = costs, namely where R(Q) = C(Q).

we used 8, because we can't use 9, since it's less than 9 shirts, is 8.8, then again 8.8 shirts is 8 shirts and then you grab another one and ripped it up by 0.8, which we're not going to do, well, unless one client wants that.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
