Respuesta :

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

Answer: 3.4875

Step-by-step explanation:

Here, According to the question,

Total amount is $23.25

[tex]100\% = 23.25[/tex]

⇒[tex]1\% = \frac{23.25}{100}[/tex]

⇒[tex]1\%= \frac{0.95}{8}[/tex]

⇒ [tex]15\%= 15\times \frac{0.95}{8}[/tex] ( By multiplying 15 on both sides)

⇒ [tex]15\%= \frac{14.25}{8}[/tex]

⇒  [tex]15\%= 3.4875 [/tex]

Thus, 15% of $23.25 is $3.4875
