t>1, so lets assume t = 2
Qty A: (2(2)+5)/3= 9/3=3
Qty B: 3(2) = 6
In this case, Qty B is greater.
Lets assume t = 1.1
QTY A: (2.2+5)/3= 7.2/3=2.4
Qty B: 3.3
So, in all the cases, Qty B is greater.

We can solve this question using matching operations

Given:
Quantity A: $$\frac{2t+5}{3}$$

Quantity B: $$3t$$

Multiply both quantities by 3 to get:
Quantity A: $$2t+5$$

Quantity B: $$9t$$

Subtract 2t from both quantities to get:
Quantity A: $$5$$

Quantity B: $$7t$$

Divide both quantities by 7 to get:
Quantity A: $$\frac{5}{7}$$

Quantity B: $$t$$

Since we're told $$t > 1$$, we know that $$t>\frac{5}{7}$$
