To convert a percentage to a decimal we divide it by 100. So, 5% = .05
To find the tax, multiply the cost by the tax rate
(.05)(11.20) = 0.56
Add this to the cost to get the total
$11.20 + $0.56 = $11.76
Answer:
There were 4 adults; including Mr. Torres
Step-by-step explanation:
- Each row in the stadium had 9 seats
- Mr. Torres sat by himself; he sat on a row with nobody else (no students, no adults)
- The arrangement of the students and the adults who sat with them on same row is: A S S S A S S S A
1 2 3 4 5 6 7 8 9
since 1 adult sat at each end of a/the row and each group of 3 students was seated between 2 adults.
So the total number of adults that were present = 3 + 1 = 4
480 people is 75 %
x people is 100 %
--------------------------
480 : x = 75 : 100
75 x = 48,000
x = 48,000 : 75
x = 640
Answer:
D ) 640 people
You have 1/4 + 1/4 + 1/4 + 3/8 + 3/8 + 5/8 + 5/8 + 5/8 + 5/8 + 1
this can reduce to 3/4 + 6/8 + 20/8 +1
6/8 = 3/4 so you have 3/4 + 3/4 + 20/8 + 1
6/4 + 20/8 + 1
you can change the denominator to 4 to make it easier=
6/4 + 10/4 + 4/4 = 20/4 = 5
