Answer:
To match the armour shirt, fila will give additional discount of 18.6%
Step-by-step explanation:
For the armour shirt, 5% of $65 is
(5/100)*65 = $3.25
The actual selling price of armour shirt is $65 - $3.25 = $61.75
If Fila first give 8% discount, and then 3%, then we will have
(8/100)*85 = $6.80
The price will be $85 - $6.80 = $78.2
Then 3% of $78.20 is
(3/100)*78.20 = $2.35
New price is $78.20 - $2.35 = $75.85
The addition % discount will be ($75.85 - $61.75)/$75.85 × 100%
= (14.1/75.85)*100
≈ 18.6%
