Total sale for the year 2019 is given by expression 1.75 x2 + 1.25 x + 7 ,where x is number auto manufactured per year .The total cost of producing x autos is given by expression 1.03 x2 + 1.21 x - 4 . What is the total profit earned by the company for the year 2019?​

Answer 1

$Given \: total \: sale \: for \: the \: year \: 2019 \\= 1.75x^{2} + 1.25x + 7 \: --(1)$

$Total \: production \: cost = 1.03x^{2} +1.21x - 4 \: --(2)$

$\red{ Total \: profit } = Total \: sale - Total \: production \:cost \\= 1.75x^{2} + 1.25x + 7 - (1.03x^{2} +1.21x - 4 ) \\=1.75x^{2} + 1.25x + 7 - 1.03x^{2} -1.21x + 4 \\ = ( 1.75 - 1.03)x^{2} + (1.25-1.21)x + 7 + 4 \\= 0.72x^{2} + 0.04x + 11$

Therefore.,

$\red{ Total \: profit } \green { = 0.72x^{2} + 0.04x + 11}$
