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%.

Step-by-step explanation:
The miles that can be travelled in the car on $30 gasoline is 240 miles (option A).
<h3>How many miles can the car travel?</h3>
The first step is to determine the total gallons in the car. The total gallons in the car can be determined by dividing the total value of the gasoline the car by the cost per gallon. Division is the process of determining the quotient of two or more numbers.
Total gallons = total value of gasoline in the car / cost per gallon
$30 / $2.50 = 12 gallons
The next step is to determine the total miles that the car can travel using the gallons available. To determine the total miles, multiply the total gallons by the number of miles that that one gallon can cover.
Total miles = miles one gallon can cover x total gallons in the car
12 x 20 = 240 miles
