Answer 3

Calculation:

To calculate how many pens Katrina could buy if the price of a pen decreased by 50%, we need to determine the original price of the pen and then calculate the new price after the discount.

Given: - Katrina can buy 12 tablets for 8 cents each.

To find the original price of the pen, we can set up a proportion:

12 tablets / 8 cents = x pens / original price of a pen

Simplifying the proportion:

12 / 8 = x / original price of a pen

Cross-multiplying:

12 * original price of a pen = 8 * x

Simplifying further:

original price of a pen = (8 * x) / 12

Now, we need to calculate the new price of the pen after the 50% discount. We can do this by multiplying the original price by 0.5 (50% is equivalent to 0.5):

new price of a pen = original price of a pen * 0.5

Finally, we can calculate how many pens Katrina could buy with her money:

number of pens = total money / new price of a pen

Let's calculate the answer step by step.

Calculation:

1. Calculate the original price of a pen: - original price of a pen = (8 * x) / 12
