Question

Screen printing a batch of shirts takes 0.4 minutes to make a shirt in addition to 4 minutes of initial set time. If it take 6.4 minutes to screen-print a batch of shirts , how many shirts are in the batch?

Answer 1

There are 6 shirts in the batch

Step-by-step explanation:

The given is:

1. Screen printing a batch of shirts takes 0.4 minutes to make a shirt

2. The initial set time is 4 minutes

3. It takes 6.4 minutes to screen-print a batch of shirts

We need to find how many shirts are in the batch

Let us represent these information in a function

Assume that there are n shirts in the batch

Then t(n) is the total time to screen-print n shirts in the batch

∵ There is initial set time = 4 minutes

∵ It takes 0.4 minutes to make a shirt

∵ The number of shirts  = n

∴ t(n) = 0.4 n + 4

∵ It takes 6.4 minutes to screen-print a batch of shirts

∴ t(n) = 6.4

∵ t(n) = 0.4 n + 4

∴ 6.4 = 0.4 n + 4

- Subtract 4 from both sides

∴ 2.4 = 0.4 n

- Divide both sides by 0.4

∴ n = 6

There are 6 shirts in the batch
