Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 13 minutes of initial set-up time. If it takes 616 minutes to screen-print a batch of shirts, how many shirts are in the batch?

Answers

Answer: 201 shirts

Step-by-step explanation:

Let x= total shirts in the batch.

Total time taken for x shirts = Initial set-up time + (Time require per shirt) × (x)

[tex]\Rightarrow\ 616= 13+3x\\\\\Rightarrow\ 3x=616-13\\\\\Rightarrow\ 3x= 603\\\\\Rightarrow\ x=\dfrac{603}{3}\\\\\Rightarrow\ x=201[/tex]

Hence, there are 201 shirts in the batch.

Question: The sum of an integer and its opposite is always, sometimes or never equal to zero?

Answers

Answer: Always

An example would be 5 + (-5) = 0

Another example is -7 + 7 = 0

The opposite of any positive number is the negative version of that number.

Adding any positive number to its negative counterpart always leads to 0.

A real world example could be "You start on the ground floor. Then you go up 9 floors, and then go down 9 floors in a building, so ultimately you're at the ground floor again". By the term "ground floor", I mean "floor 0".
