Answer:
10.5%
Step-by-step explanation:
The fraction Angie sold at 130% of the cost price was 350/500 = 0.7. The remaining 0.3 of the dresses were sold at 130%/2 = 65% of the cost price.
Angie's net on the deal was ...
(0.7)(130%) +(0.3)(65%) = 91% +19.5% = 110.5%
where 100% is Angie's cost price. Her profit is this percentage less 100%.
Angie's profit as a percentage of her cost price was 10.5%.
_____
<em>Alternate solution</em>
Obviously, you can work out the cost price of each dress ($25) and the marked up price ($32.50). Then you can work out the revenue for 350 dresses ($11,375) and the revenue from the sale of the remaining 150 dresses at half price ($16.25 × 150 = $2,437.50). Angie's total revenue ($13,812.50) less the cost price is her profit ($1,312.50). Divided by her original cost, this will be her profit: $1,312.50/$12,500 × 100% = 10.5%.
Answer:
5 Hours, 9 Minutes, 0 Seconds
Step-by-step explanation:
↝ Form into 
where a > 0 (Optional)
↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula
↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝
Therefore, the answer for Complex Number System is (5±√7i)/2
Answer:
225
Step-by-step explanation:
A = 5. 3A = 3(5) cubed. So 3 times 5 is 15. 15 cubed is 225.
