If coal is mined at $35.99 per short ton, how much is the price per kg? Use dimensional analysis to solve. 1 short ton = 907 kg.

cricket20 [7]

The cost of 1kg of coal mined from the ore is $0.0397

Data;

1 ton = $35.99
1kg = ?

To find the cost of 1kg of coal, we can simply and equate 1 ton to its equivalent in ton and the solve.

$1ton = 907kg\\$

let's write this and equate it

1 ton = $35.99

907kg = $35.99

1kg = x

Let's cross multiply both sides and solve for x

$907kg = \$35.99\\1kg = x\\x = \frac{1 * 35.99}{907} \\x = \$0.0397$

The cost of 1kg of coal is $0.0397
