(0.15)($45)
(1.15)($45)
$45 + 0.15
1 + (0.15)($45)

Answer 1

1.15($45)

Explanation:

Answer 2

Option B: 1.15($45) is the correct answer.

Explanation:

Given that:

Total amount of restaurant bill = $45

Tip = 15%

As the bill would be 100% and a 15% tip will be added.

Thus total bill,

Total bill = (100+15)% = 115% of restaurant bill

Total bill =
`(115)/(100)(45)`

Total bill = 1.15($45)

Hence,

Option B: 1.15($45) is the correct answer.
