Question

You buy 3 trackers and a wireless charger. You use a coupon for 15% off your total purchase. You pay a total of $45.22 after using the coupon. The original price of the charger is $15.64. What is the original price of one charger

Answer 1

$12.52

Explanation:

Let's denote the original price of one charger as "C" in dollars.

The original price of 3 trackers is 3 times the price of one tracker, which

The original total price before the 15% coupon discount is the sum of the charger and the trackers' prices:

Original total price = Original price of 3 trackers + Original price of 1 charger

Original total price = 3C + 15.64 dollars

Now, we know that you paid a total of $45.22 after using the 15% coupon discount. This means that the discounted total price is 85% (100% - 15%) of the original total price:

Discounted total price = 0.85 * Original total price

So,

0.85 * (3C + 15.64) = 45.22

Now, let's solve for C:

0.85 * (3C + 15.64) = 45.22

Divide both sides by 0.85:

3C + 15.64 = 45.22 / 0.85

3C + 15.64 = 53.2

Subtract 15.64 from both sides:

3C = 53.2 - 15.64

3C = 37.56

Now, divide by 3 to find the original price of one charger:

C = 37.56 / 3

C = 12.52

So, the original price of one charger is $12.52.
