Question

Unit profit on a Nissan Altima and a Nissan Sentra average $1,200 and $850, respectively, at Bob's car dealership in suburban Milwaukee. Last month the dealership sold a total of $120 cars for an overall profit of $130,350. Calculate (a) number of Altima sold, (b) number of Sentras sold, (c) total profit for Altimas, and (d) total dollar profit for Sentras.

 

(a)?

(b)?

(c)?

(d)?

 

 

 

Answer 1

let altima = a and sentra = s

total # of cars  is a + s = 120; a = 120 - s

substitute the value of a (altima) into the equation for the total dollars profit equation 1200a + 850s = $130,350

1200(120 - s) + 850s = 130350

s = 39 cars

a = 120 - 39 = 81 cars

total $ s = 39 (850) = $33,150

total $ a = 81 (1200) = $97,200
