Let the two numbers be x and y
As given, the difference of two numbers is 3, so
or ....(1)
And their sum is 25, so
.....(2)
Putting x=3+y in equation (2)
As, x+y=25
So the two numbers are = 14 and 11
We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).
s = the number of student tickets sold
a = the number of adult tickets sold
The drama class sold 25 more student tickets than adult tickets to the fall play
s = a + 25
The class collected $660 from ticket sales:
6s + 3a = 660 divide both sides by 3
2s + a = 220
by solving the system of equations
s = a + 25
2s + a = 220
we find
s = 81.67 student tickets
a = 56.67 adult tickets
Answer:
23 dollars
Step-by-step explanation:
so to figure out how much more you grab 20 and multiply by .15 as percent and you will get 3 dollars more so 23
