According to the image, the table shows a relationship that is not proportional. First of all, you cannot multiply a number by 0 and get something other than 0. Anything multiplied by 0 is always 0.
Second, the rule is different for each row.
2x5=10
4x4=16
6x3.6=22
A proportional relationship must increase by the same amount, and this does not, which means it is not proportional.
I think what you are looking for is 5x=300 therefore x=60 so at 60cars he would start to make more.
Answer:
p = 26 ; q = 60
Step-by-step explanation:
Given the demand and supply functions :
Supply function:
4p - q = 44
Demand function :
(p + 2)q = 1680 - - - - (1)
p = price ; q = quantity
Expressing supply function interms of q
4p - 44 = q - - - - - (2)
Plug 4p - 44 = q into (1)
(p + 2) (4p - 44) = 1680
4p²- 44p + 8p - 88 = 1680
4p² - 36p - 1768 = 0
p² - 9p - 442p = 0
p(p - 26) + 17(p-26) = 0
(p + 17) = 0 ; (p - 26) =0
p = - 17 or p = 26
Price of commodity can't be negative, Hence, p = 26
From q = 4p - 44
Put p = 26
q = 4(26) - 44
q = 104 - 44
q = 60
p = 26 ; q = 60
