5 for $30
4 for $15
8 for $26
10 for $45
To determine the best deal for the t-shirts, we can calculate the price per shirt for each option.
Option 1: 5 for $30
Price per shirt = $30 / 5 = $6
Option 2: 4 for $15
Price per shirt = $15 / 4 = $3.75
Option 3: 8 for $26
Price per shirt = $26 / 8 = $3.25
Option 4: 10 for $45
Price per shirt = $45 / 10 = $4.50
From the calculations, we can see that the best deal is Option 3: 8 t-shirts for $26, with a price per shirt of $3.25.

Apologies for the mistake. Let's evaluate the given options again to determine the best deal:
Option 1: 5 for $30
Price per shirt = $30 / 5 = $6
Option 2: 4 for $15
Price per shirt = $15 / 4 = $3.75
Option 3: 8 for $26
Price per shirt = $26 / 8 = $3.25
Option 4: 10 for $45
Price per shirt = $45 / 10 = $4.50
From the calculations, we can see that the best deal is still Option 3: 8 t-shirts for $26, with a price per shirt of $3.25.
