One meter of electrical cord costs 3 dollars. How much should one pay for 4 meters?? Please help me out here.
Snowcat [4.5K]

Answer:

$12

Step-by-step explanation:

The best way to do this is with a simple ratio. If you pay $3 for one meter, then for 4 meters, you’d pay $12. You BOUGHT 4 times more cord, which means you’d PAY 4 times more. Thus, 3 x 4 = 12!

Or with ratios:

1 meter : $3

multiplying both sides by 4

4 meters : $12
