Let the number of adult be x and the number of children be y.
There is a total of 11 people
x + y = 11
Total cost of tickets is $228
22x + 15y = 228
x + y = 11 ----------------- (1)
22x + 15y = 228 ---------(2)
From (1):
x+ y = 11
x = 11 - y --- sub into (2)
22 (11 - y) + 15y = 228
242 - 22y + 15y = 228
-7y = 228 - 242
-7y = -14
y = 2 ---- sub into (1)
x+ 2 = 11
x = 9
Number of adult tickets = 9
Number of child tickets = 2
A is the answer as it will go in a full circle in order to map onto itself
Answer:
c < 3
Step-by-step explanation:
We can first add 10 to both sides to remove the -10.
This is additive property of equality, where both sides must stay the same ratio, so we always use the same property on both sides unless simplifying what is already there.
So we now have c + 3c < 12.
As I mentioned less than 2 full sentences above, we can simplify without doing the same thing to both sides if it is already there, so we can add the c + 3c since it is already there.
We now have 4c < 12.
Then, we divide both sides by 4 to get c, and again mentioned about 4 sentences above, we need to divide both sides.
So we now should have c < 3.
NOTE: IF YOU HAVE A SIMILAR PROBLEM WHERE THE VARIABLE IS NEGATIVE LIKE -4a FOR EXAMPLE, THE INEQUALITY SIGN CHANGES DIRECTION. IN THIS PROBLEM, THAT IS NOT THE CASE, BUT FOR FUTURE PROBLEMS, THAT IS A <u>MUST</u>.
