A 6 pack of undershirts costs $13.98. This is $3.96 less than the cost of buying 6 individual shirts. If each undershirt costs the same amount, how much does each undershirt cost when purchased individually?

Answer 1

Let the cost of each individual undershirt be denoted as \( x \).

The total cost of buying 6 individual undershirts is \( 6x \).

According to the information provided, the cost of the 6-pack is $13.98, which is $3.96 less than the cost of buying 6 individual shirts. We can set up the following equation:

\[ 6x - 3.96 = 13.98 \]

To isolate \( 6x \), we add \( 3.96 \) to both sides of the equation:

\[ 6x = 13.98 + 3.96 \]

Calculating the right side:

\[ 13.98 + 3.96 = 17.94 \]

Now we have:

\[ 6x = 17.94 \]

Next, we solve for \( x \) by dividing both sides by 6:

\[ x = \frac{17.94}{6} \]

Calculating the division:

\[ x = 2.99 \]

Thus, the cost of each undershirt when purchased individually is \( \boxed{2.99} \).
