Which of the following expressions could give the total amount of a $45 restaurant bill with a 15% tip added on?
vazorg [7]

Answer:

$51.75

Step-by-step explanation:

Given

Total amount of bill, x= $45

Tip Percent=15%

⇒15% on $45 is to be paid extra as tip, other than the already paying $45

⇒Tip=\frac{15}{100}\times x=\frac{15}{100}  \times45=6.75

So <em>total amount to be paid</em>= Bill+ tip

= x + tip=x+\frac{15}{100} x=1.15x=1.15\times45

=$51.75
