Answer 1

10%=2.33 + half that is 1.17= 3.50 23.25×.15= 3.4875

Answer 2

Answer: 3.4875

Explanation:

Here, According to the question,

Total amount is $23.25

`100\% = 23.25`

⇒
`1\% = (23.25)/(100)`

⇒
`1\%= (0.95)/(8)`

⇒
`15\%= 15* (0.95)/(8)` ( By multiplying 15 on both sides)

⇒
`15\%= (14.25)/(8)`

⇒
`15\%= 3.4875`

Thus, 15% of $23.25 is $3.4875
