5 times 7 is 35 plus 3 is 38
Answer:p = (2100 - x)/25
Step-by-step explanation:
According to the law of demand, when the price,p of the brand of MP3 players is is high, the quantity,x of the brand of MP3 players demanded would be low and when the price,p of the brand of MP3 players is is low, the quantity,x of the brand of MP3 players demanded would be high.
To derive the demand equation, we would apply the slope intercept form of equation which is expressed as
y = mx + c
Where
m = slope
c = intercept
The slope, m would be
(y2 - y1)/(x2 - x1)
Slope = (1100 - 100)/(40 - 80) = 1000/-40
Slope = - 25
To find the y intercept, we would substitute m = - 25, y = 1100 and x = 40 into y = mx + c. It becomes
1100 = - 25 × 40 + c
1100 = - 1000 + c
c = 1100 + 1000 = 2100
y = - 25x + 2100
Therefore, the demand equation is
x = - 25p + 2100
25p = 2100 - x
p = (2100 - x)/25
Stevic's total earnings after delivering 15 papers on Sunday is $180.
Stevic's total earnings after delivering 15 papers on Saturday is $60.
<h3>What is the total earning?</h3>
Multiplication is the mathematical operation that is used to determine the product of two or more numbers. In order to determine the total earnings, multiply earning per newspaper delivered by total earnings.
Total earnings on Sunday= $12 x 15 = $180
Total earnings on Saturday = 4 x 15 = $60
