Step-by-step explanation:
The <u>cost</u> of his meal at a cafe is $36.00 and Cristofer wants to leave a <u>10% tip</u>. So to find what is his <u>total bill</u>, you have to <u>count 10% from</u> $36.00.
Note that
$36.00 -- 100%,
$x -- 10%.
Write aproportion:

Then

Therefore, the total bill consists of $36.00 for the meal and $3.60 tip:
$36.00 + $3.60 = $39.60.
Answer: $39.60
Quadratic formula: x equals negative b plus or minus the square root of b squared minus 4 ac all over 2a
a=2 b=5 c=1
x=(-5+/5^2-4(2)(1))/2(2)
-5+/25-8/4
-5+/17/4
(-5+4.12)/4
-0.877/4
-0.219
x=(-5-/5^2-4(2)(1))/2(2)
-5-/25-8/4
-5-/17/4
(-5-4.12)/4
-9.12/4
-2.28
x=-0.219 or x=-2.28
If you factor c + 0.09c, we get c(1 + 0.09), which is the same as (1 + 0.09)c.
If we add the numbers inside the parentheses (1 + 0.09)c we get 1.09c.
The answer is choice B and E.
