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
Answer:
i would say
y = ( 77 - x ) / 2
Step-by-step explanation:
2x + 4y = 123 + 31
2x +4y = 154
4y = 154 -2x
y = ( 154 - 2x ) / 4
y = ( 77 - x ) / 2
1 + 4 = 5 (5 parts)
First, set the equation up as y=mx+b then the perpendicular will be the opposite slope of your original slope
