Answer:
$208.30
Step-by-step explanation:
<h2>Discount:</h2>
Let the original price be $ x
Discount % = 12%
Discount = $ 25
12% of x = 25


= $ 208.30
Tess is correct about figuring 10% but he added 2 of them together which is like adding 10% +10% which is 20% not 15%.
he should have taken 1/2 of the 4.60 for 5% since 5 is half of 10
half of 4.60 = 2.30
then add that to the 4.60
4.60 +2.30 = 6.90 is 15%
Answer:45,311
45,301+10=45,311
I hope this is good enough:
