Answer:
adult ticket =$8 child ticket = $4
Step-by-step explanation:
2x =y
2y + 5x =36
4y + X=36
y =8 so X=4
This question is that 1 1/2
Answer:
3A : 3(a)+8(b)+2(c)
3B: 3(20)+8(8.50)+2(40)=208
3C: 208-15%=208*0.15=31.2
208-31.2=176.8
3D: 176.8+6%=176.8*1.06
187.41
-1*-6=6
-1+(-6)=-7
Hope that helped
