Price of a printer. Laura paid $219.45, including

5% tax, for an all-in-one color printer. How much
did the printer itself cost?

219.45 / 1.05 = ?

The price of a printer was reduced from 400 to 280. What was the percentage decrease?

To find out how much the printer itself cost, we need to first calculate the cost of the tax and subtract it from the total amount paid by Laura. Here's the step-by-step process:

1. Calculate the tax amount:
Tax rate = 5% = 0.05
Tax amount = Total amount paid - Printer cost
Tax amount = 0.05 * Total amount paid

2. Deduct the tax amount from the total:
Printer cost = Total amount paid - Tax amount

Let's do the calculations:

1. Calculate the tax amount:
Tax amount = 0.05 * $219.45 = $10.97

2. Deduct the tax amount from the total:
Printer cost = $219.45 - $10.97 = $208.48

Therefore, the cost of the printer itself is $208.48.
