Question

6. The cost of 12computers is $4800. How much does 15 computers costs.

Answer 1

Answer: $6000

Explanation:

Let x = # of computers

Step 1: 12x = $4800

Step 2: Divide by 12. x = 400

Now we know 1 computer = $400.

Therefore, 15 computers ($400 each) can be represented with the equation:

15 x $400 = $6000.

Answer 2

$6000

Explanation:

12 = 4800

Divide both sides by 12 to get the price of 1 computer.

1 = 400

Multiply by 15...

15 = 6000
