So baically
reresent
s=number of studne tickes bouthgt
a=number of adult tickets bought
300 tickest sold
total=300
a+s=300
value=rate times number of peple
student value=4s
adults value=10a
total value=1950
4s+10a=1950
a. system of equations are
s+a=300
4s+10a=1950
b. solve
s+a=300
4s+10a=1950
a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution
4s+10a=1950
<u>-4s-4a=-1200 + </u>
0s+6a=750
6a=750
divide 6
a=125
subsiute
s+a=300
s+125=300
subtract 125
s=175
a. s+a=300
4s+10a=1950
b. solution above
175 students
125 aduls
Answer:
74
Step-by-step explanation:
What I'm getting at, is that you need to add all the hour sold cups up, and then double it because she expects to sell twice as much. 15 + 11 +5 +6 = 37, and 37 doubled is 74
I believe the Answer is A
To get Fractions equal, you can multiply the fraction By any number you want: (a/b) = k.(a/b)
So multiply 3/5 by 3: (3/5).3 = 9/15
Multiply it by 2: 2.(3/5) = 6/10
3/5 = 9/15 = 6/10 = 0.6
Hope this Helps! :)
