Answer:
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
Answer:
c. $2.800
Step-by-step explanation:
In this case we can solve it using a 2x2 system of equations, like this:
let x: value of cars
let y: value of trucks
So:
6 * x + 3 * y = 4800
8 * x + 1 * y = 4600 => y = 4600 - 8 * x
Replacing, we are left with that:
6 * x + 3 * (4600 - 8 * x) = 4800
6 * x + 13800 - 24 * x = 4800
6 * x - 24 * x = 4800 - 13800
-18 * x = -9000
x = -9000 / -18
x = 500
Now to calculate and:
y = 4600 - 8 * 500
y = 600
If selling 2 cars and 3 trucks, it would be:
2 * 500 + 3 * 600 = 2800
I would earn $ 2.800
