77julia77 [94]

Juan paid 70.16 % of the original price of the jacket.

Step-by-step explanation:

Step 1:

Given details, Original Selling Price of the jacket = 85.50

New Selling Price of the jacket = 59.99

Step 2:

To determine what percentage of the old price is the new price, we have to use percentage calculation.

x/100\times 85.50 = 59.99

Step 3:

Substitute in the formula, the given values

x = (59.99/85.50) \times 100

  = (0.7016) \times 100

  = 70.16

Therefore, percentage paid is 70.16%
