Answer 1

Answer: The two answers are 1.08T and (1 + $\frac{8}{100}$ )T.

Step-by-step explanation:

Try multiplying 1.08 times any random number. If you use 5,  1.08 times 5 gives you 5.4.  This makes sense. Solve the other other expression as well and substitute T with the SAME number that you used before (5). Hope that helps!
