Given :
Marcus bought a booklet of tickets to use at the amusement park.
He used 50% of the tickets on rides, 13% of the tickets on video games, and the rest of the tickets in the batting cage.
To Find :
Marcus says he used 10% of the tickets in the batting cage.
Solution :
We know sum of all the percentage should be equal to 100.
So,
( % used on rides ) + ( % used on video game ) + ( % used in batting cage ) = 100
Let, % of ticket spend on batting cage is x.
50 + 13 + x = 100
x = 100 - ( 50 + 13 )
x = 37%
So, Marcus used 37% in batting cage.
Therefore, the statement by Marcus that he use 10% of the ticket in the cage is wrong.
No, i do not agree. To find this out, we will have to convert all of them into either decimals or percents. Let's convert these all into percents. A percent means 'out of 100', so if we add the percents all together, they should equal to 100. The rides is 50%. To convert 1/3 into a percent, divide the numerator by the denominator. You will get a decimal, so then multiply that by 100 or move the decimal two places to the right. So, 1 divided by 3 is equal to approximately 33%. Let's add 50 and 33 together. The total is 83%. So, like I said, a percent is out of 100. Subtract 83 out of 100 and you will get 17. So, the remaining percent has to be 17 percent, not 10%.
Hope it helps :)
