A salesperson earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns $4,800. A person selling 8 cars and 1 truck earns $4,600. How much does a salesperson earn for selling 2 cars and 3 trucks?
a. $2,500.
b. $2,700.
c. $2,800.
d. $3,000.

C; $2,800

Step-by-step explanation:

Let the amount earned per truck sales be $t and the amount earned per car sales be $c

Selling 6 cars and 3 trucks earned a total of $4,800

This mathematically means;

6c + 3t = $4,800 •••••••••(i)

Selling 8 cars and 1 truck earned a total of $4,600

This mathematically means;

8c + t = $4,600 ••••••••(ii)

Now, we solve both equations simultaneously;

From equation ii, t = 4600 -8c

we plug this in equation i

6c + 3(4600-8c) = 4,800

6c + 13,800 - 24c = 4,800

18c = 9000

c = 9,000/18

c = 500

in second equation;

t = 4,600 - 8c

inputing the value of c, we have;

t = 4,600 -8(500)

t = 4,600 - 4,000

t = 600

Now we want to know how much commission earned on selling 2 cars and 3 trucks.

That will be 2c + 3t = 2(500) + 3(600) = 1000 + 1,800 = $2,800

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

answer is  

c.
