Answer:
a=112
b=6
c=280
Step-by-step explanation:
you just plug the number into the equation
28x=y
where x is the gallons
and y is the total miles
A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
Step 2: it should be P-2x, not +.
Hope this helped :)
C + a = 132.....a = 132 - c
5.10c + 9.60a = 898.20
5.10c + 9.60(132 - c) = 898.20
5.10c + 1267.20 - 9.60c = 898.20
5.10c - 9.60c = 898.20 - 1267.20
-4.50c = - 369
c = -369/-4.50
c = 82 <=== child tickets sold
