Let x be the number of children and t, the number of adults.
x + y =153
5.2x + 8.4y = 1013.2
Solving those equation will give:
x = 85 tickets sold to the kids ( and 68 tickets for adults)
volume is 180
surface area (area) is 105.97
The proportion is 1:10. You can get this by dividing both 50 and 500 by 50.
First we define variables.We have then:D: monthly data.C: total cost.
For Plan A:
C = 5D +30
D: [5, 8]
We evaluate for D = 8
C = 5 (8) +30
C = 40 + 30
C = 70 $
For Plan B:
C = 2D +50
D: [5, 8]
We evaluate for D = 8
C = 2 (8) +50
C = 16 + 50
C = 66 $
Answer:
the best choice for him is plan B:
C = 2D +50
