A broker takes 2% as commission for the sale of property of value up to rupees 3,00,000. If the sale price is more than this, th
astra-53 [7]

Answer:

The broker's commission was rupees 8,250

Step-by-step explanation:

Selling price of property = rupees 450,000

The sale price is higher than rupees 300,000

Commission for rupees 300,000 = 2% × rupees 300,000 = rupees 6,000

Remaining amount = rupees 450,000 - rupees 300,000 = rupees 150,000

Commission for the remaining amount = 1.5% × rupees 150,000 = 0.015 × rupees 150,000 = rupees 2,250

Total commission = rupees 6,000 + rupees 2,250 = rupees 8,250

The graph shows the altitude, a, of a plane, in feet, after t minutes. What is the rate of ascent of the airplane?
alexira [117]

The rate of ascent is also known as the slope. To find the slope, we will follow the steps below.

Step 1) Choose two points on the line

Point 1: (4, 500)

Point 2: (8, 1000)

Step 2) Use the slope formula to find the slope

m = (y2 - y1) / (x2 - x1)

m = (1000 - 500) / (8 - 4)

m = 500 / 4

m = 125 feet per minute

Hope this helps! :)
