Answer 2

Price before tip "b" of Kia’s dinner is $ 35

Solution:

Given that kia dinner bill is $ 40.25 which inclused a 15% tip

To find: price before tip "b" of Kia’s dinner

Let us first find the tip amount paid by Kia

Let "b" be the dinner bill before tip

Given that dinner bill is $ 40.25 which inclused a 15% tip

So, 15 % of "b" is the tip amount paid

tip amount paid = 15 % of "b"

`\text {tip amount paid }=15 \% * b`

`\text {tip amount paid }=(15)/(100) * b=0.15 b`

Now we can say,

Dinner bill including tip = dinner bill before tip + tip paid

$ 40.25 = b + 0.15b

40.25 = 1.15b

b = 35

Thus price before tip "b" of Kia’s dinner is $ 35
