Answer:
1. x=0 y=-20
2. x=0 y=7.5
Step-by-step explanation:
Since Max's deck of cards contains the same number of blue cards as Barry's,
letting x as the number of red cards in Max's deck of card
40 / x = 8 / 9
Solving for x
360 = 8x
x = 45
There are a total of 40 + 45 = 85 cards in Barry's deck of cards
Let the admission price for adults be 'x' and that of children be 'y'
Equation Formation.
2 x + 3 y = 80............equation(i)
3 x + y = 99.............equation(ii)
y = 99 - 3 x
2 x + 3(99 - 3 x) =80
2 x +297 - 9 x = 80
- 7 x = -217
x = 31
y = 99 - 3x
y = 99 - 3×31
y = 99 - 93
y = 6
Answer ⇒ Adults = $31
Children = $6
