This equation shows how the time required to screen-print a batch of shirts is related to the number of shirts in the batch.

t = 4s + 3

The variable s represents the number of shirts in the batch, and the variable t represents the time required to screen-print the shirts. How long does it take to screen-print a batch of 4 shirts?

1 answer

To find out how long it takes to screen-print a batch of 4 shirts, we can substitute \( s = 4 \) into the equation \( t = 4s + 3 \).

Substituting:

\[ t = 4(4) + 3 \]

Calculating:

\[ t = 16 + 3 = 19 \]

Therefore, it takes 19 minutes to screen-print a batch of 4 shirts.
