Answer: the answer is 3/2
I know this because my brain is right
Here are two slightly different ways to look at it.
Both ways do exactly the same thing.
<u>Way #1:</u>
Divide (the new number) by (the old number)
349 / 320 = 1.090625
Change the quotient 1.090625 to percent.
To change any number into percent, multiply it by 100, or move the decimal point 2 places to the right.
1.090625 ==> 109.06 %
The new number (349) is 109.06% of the old number (320).
But the old number was 100% of itself. So the new number
is <em>9.06% more</em> than the old number was.
================================
<u>Way #2:</u>
How much bigger is the new number ?
(349 - 320) = 29 bigger
Divide the increase by the old number:
29 / 320 = 0.090625
Change the quotient to a percent.
0.090625 = 9.06%
The <em>increase</em> is<em> 9.06%</em> of the old number.
Answer: See bolded equations
Step-by-step explanation:
The system of equations can be used to solve this problem. C is child ticket and a is adult ticket.
Equation 1
3c+4a=1740
This equation comes from the cost of the tickets. 3c is the cost of $3 per child ticket and 4a is the cost of $4 per adult ticket. 1740 is the total amount collected.
Equation 2
c+a=530
This comes from the number of tickets sold. The c+a is the total of child and adult tickets sold and 530 is the total amount of tickets.
