Tickets to a country fair for four adults is and five children cost $33.00. an adults ticket costs $1.50 more than a child's ticket. find the cost of the adult ticket.

an adult ticket costs $4.5

Step-by-step explanation:

Let x represent the cost of one adult's ticket.

Let y represent the cost of one child's ticket.

Tickets to a country fair for four adults is and five children cost $33.00. This means that

4x + 5y = 33 - - - - - - - - - - - 1

An adults ticket costs $1.50 more than a child's ticket. This means that

x = y + 1.5

Substituting x = y + 1.5 into equation 1, it becomes

4(y + 1.5) + 5y = 33

4y + 6 + 5y = 33

4y + 5y = 33 - 6

9y = 27

y = 27/9 = 3

x = y + 1.5 = 3 + 1.5 = 4.5

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
