Given m<ABC=88°.
<ABD=2x and <CBD=x-2.
Soltution. m<ABC is the sum of angles m<ABD and m<CBD.
So, we can setup an equation as
m<ABD + m<CBD = m<ABC.
Plugging values of m<ABD, m<CBD and m<ABC in above equation, we get
2x + x-2 = 88
Combining like terms 2x+x=3x, we get
3x-2=88.
Adding 2 on both sides,
3x-2+2=88+2.
3x=90.
Dividing both sides by 3, we get
3x/3=90/3
x=30.
Plugging value of x=30 in given values of m<ABD and m<CBD
<ABD=2x = 2(30) = 60° and
<CBD=x-2 = x-2 = 30-2 =28°.
Therefore, <ABD =60° and <CBD=28°.
The domain of the logarithm function is (0, ∞) and the range of the logarithm function will be (-∞, ∞)
<h3>What are domain and range?</h3>
The domain means all the possible values of the x and the range means all the possible values of the y.
The table is shown below.
Let the logarithm function with the variables x and y. Then we have
y = logₐ x
At x = 25, the value of y will be 2. Then the value of a will be
2 = logₐ 25
2 = 2 logₐ 5
1 = logₐ 5
Then 1 can be written as
1 = log₅ 5
Then on comparing, the value of a will be
a = 5
Then the logarithm function will be
y = log₅ x
Then the domain of the logarithm function is (0, ∞) and the range of the logarithm function will be (-∞, ∞)

First, you have to add up the cost of each meal and drink:
12.50 + 12.50 + 1.50 + 1.50 = 28
$28 is the cost before the tip. Now multiple 28 by .18 to find the tip:
28 x .18 = 5.04
The tip was $5.04. Add the 28 and the 5.04 to get the total cost:
28 + 5.04 = 33.04
ANSWER:
The total cost was $33.04
