5t represents the cost of 5kg of oranges, and t represents the cost of 1kg of oranges. 5t could also be shown as 5\times T.

Work Step by Step

5t means the product of 5 and t. If we take the variable t as the cost of 1 kg of oranges, then by the above definition, 5t represents the cost of 5kg of oranges. As t represents the cost of 1kg then t\times 5 would equal 5kg of oranges. As the value of t is unknown we can leave the equation as 5t.
