A car dealership sells a car in a basic model (b) the fully-loaded model (f) for $20,000 and $25,000 respectively. During the month of June, the dealership sells 40 of these cars with sales totaling $880,000. How many of each model does the dealership sell? Which system of equations matches the situation? A. {b + f = 40 {25b + 20f = 880 B. {b + f = 880 {20b + 25f = 40 C. {b + f = 920 {20b + 25f = 880 D. {b + f = 40 {20b + 25f = 880

OpenStudy (phi):

how many cars did he sell total ?

OpenStudy (anonymous):

40 right?

OpenStudy (phi):

the dealership sells 40 of these cars yes. so I would look for an equation that shows the number of "b" and "f" added together equals 40. which choices show that ?

OpenStudy (phi):

can you find an equation that shows b and f added together that equals 40 ?

OpenStudy (anonymous):

A and D

OpenStudy (phi):

next, how much does a "b" cost ? (based on what they tell you )

OpenStudy (anonymous):

$20,000?

OpenStudy (phi):

yes. and if you sold 3 of them (for example) you would get 3*20000 or if you have "b" of them (b is some unknown number) you would get b*20000 it looks like they left off the 1000's (which is ok), so I would look for 20b as part of the equation. either A or D has to have that term.

OpenStudy (anonymous):

sO D?

OpenStudy (phi):

yes, and as a double check the other type costs 25 and they sell "f" of them so 20 b + 25 f is how much they would get. and that equals 880 and that is what D says: 20b + 25f = 880
