Consider that your profit-maximizing quantity of 500 can be produced at an average cost per unit of $9 and sold for a market pri
timama [110]

Based on the quantity sold and the price, the profit per unit is <u>$5</u> and the total profit is<u> $2,500</u>

The profit made from each unit sold can be found as:

<em>= Market price - Average cost </em>

= 14 - 9

= $5

The total profit would therefore be:

<em>= Profit per unit x Number of units sold </em>

= 5 x 500

= $2,500

In conclusion, the profit per unit is $5 and the total profit is $2,500

kirill115 [55]

Answer:

I'm pretty sure that the answer would be 229/236.

Step-by-step explanation:

Ok so. Since the results of the test is 229 for a girl and the results for a boy is 7. So i'm pretty sure what to do is combine both the results and keep that as the denominator. And then the numerator will be the result. So in this case the numerator would be 229 and the denominator would be 236.

I hope this helped, have a great day!!!

Trevor took one of his friends out to lunch. The lunches cost $248.40 and he paid 12.5% sales tax. If Trevor left a 15% tip on t
bixtya [17]
He paid ...

-- The cost of the lunches      (100%  =  1.00 of it)    

-- 15% of the cost as a tip    (15%  =  0.15 of it)

-- 12% of the cost as sales tax  (12%  =  0.12 of it)

Total that he paid = (1.00 + 0.15 + 0.12)  =  1.27 of $248.40

                                                           =      $315.47   .

Trevor is one generous guy !
