Answer:
The fan = x = 400
The heater = y = 3600
Step-by-step explanation:
Let the cost price of
The fan = x
The heater = y
Aaya bought a fan and a heater for Rs 4,000.
x + y = 4000
x = 4000 - y
He sold the fan at a profit of 25%
25% × x = 0.25x
And the heater at a loss of 5%.
5% × x = 0.05y
If he gained 7% on his total outlay, at
Hence:
0.25x + 0.05y = 7% × 4,000
0.25x + 0.05y = 280
Note:
x = 4000 - y
Hence:
0.25(4000 - y) + 0.05y = 280
1000 - 0.25y + 0.05y = 280
Collect like terms
-0.25y + 0.05y = 280 - 1000
-0.20y = -720
y = -720/0.20
y = 3600
x = 4000 - y
x = 4000 - 3600
x = 400
Hence, the price that he bought each item is given as:
The fan = x = 400
The heater = y = 3600
The answer to this question is -2
Two expressions that represent the sale price of the pillows are (p-0.05p) and 0.95p.
Step-by-step explanation:
Let,
Regular price of pillow = p
Mark down = 5% = 
Amount of mark down = 0.05p
Amount after mark down = Regular price - Mark down amount
Amount after mark down = p - 0.05p
Taking p common = p(1-0.05) = p(0.95) = 0.95p
Two expressions that represent the sale price of the pillows are (p-0.05p) and 0.95p.

Answer:
Equation : y = 2x + 3
Step-by-step explanation:
By considering any two coordinates from the line.
For example: I choose (0, 3) and (2, 7)
<em><u>slope :</u></em>
<em><u /></em>
<em><u /></em>
<em><u>Equation :</u></em>

Answer:
choose the first
Step-by-step explanation:
When h=0, T is the highest (because the temperature is highest at noon)
And knowing that the temperature difference in the world cannot exceed 60 degrees in a day, only the first choice is common sense.
