20/100 = x/12
The 20/100 in the expression represents the 20%. The x in this scenario is the unknown amount in which the person will tip. The /12 is the cost of the original price. So, in order to find the value of x, you would need to cross multiply.
x = $2.40
The total cost would be $2.40 + $12.00 = $14.40
Answer:
The circumference of the circle is 75.36 miles
Step-by-step explanation:
Given
Radius, r = 12 miles.
Circumference is calculated using the following formula.
C = 2πr
take π as 3.14
substitute 12 for r in the formula above.
C = 2 * 3.14 * 12
C = 75.36 miles.
The circumference of the circle is 75.36 miles
Answer:
36.4%
Step-by-step explanation:
Actual wait time is 55 minutes
