Question

Christopher has breakfast at a cafe and the cost of his meal is $36.00. Because of the service, he wants to leave a 10% tip.

What is his total bill including tip?

Answer 1

The total bill including tip is $39.6.

Explanation:

As given

Christopher has breakfast at a cafe and the cost of his meal is $36.00. Because of the service, he wants to leave a 10% tip.

10 % is written in the decimal form .

`= (10)/(100)`

= 0.10

Tip price = 0.10 × Cost of meal

= 0.10 × 36

= $ 3.6

Total bill including tip = Cost of bill + Tip cost

= $36 + $3.6

= $ 39.6

Therefore the total bill including tip is $39.6.

Answer 2

The cost of his meal at a cafe is $36.00 and Cristofer wants to leave a 10% tip. So to find what is his total bill, you have to count 10% from $36.00.

Note that

$36.00 -- 100%,

$x -- 10%.

Write aproportion:

`(\$36.00)/(\$x)=(100\%)/(10\%).`

Then

`\$x=(\$36.00\cdot 10\%)/(100\%)=\$3.60.`

Therefore, the total bill consists of $36.00 for the meal and $3.60 tip:

$36.00 + $3.60 = $39.60.

Answer: $39.60
