To determine how much Jamila will pay for the jeans under both scenarios, we'll need to calculate the final prices based on the original price of $45.00, first applying the 20% discount and then the $10 discount, and vice versa.
Part A: 20% Discount First
-
Calculate the 20% discount: \[ 20% , \text{of} , 45.00 = 0.20 \times 45.00 = 9.00 \]
-
Subtract the 20% discount from the original price: \[ 45.00 - 9.00 = 36.00 \]
-
Apply the $10 instant savings: \[ 36.00 - 10.00 = 26.00 \]
So, if the 20% discount is applied before the $10 discount, Jamila will pay $26.00.
Part B: $10 Discount First
-
Apply the $10 instant savings first: \[ 45.00 - 10.00 = 35.00 \]
-
Now calculate the 20% discount on the new price: \[ 20% , \text{of} , 35.00 = 0.20 \times 35.00 = 7.00 \]
-
Subtract the 20% discount from the new price: \[ 35.00 - 7.00 = 28.00 \]
So, if the $10 discount is applied before the 20% discount, Jamila will pay $28.00.
Summary of Results:
- Part A: $26.00 (20% discount first)
- Part B: $28.00 ($10 discount first)
