One adults ticket to an amusement park costs d dollars. One child's ticket costs $19 less than twice the cost of an adults ticket. Write and simplify an expression for the cost of one child's ticket. If an adults ticket is $28, what is the cost of a child's ticket?
c = 2d-19
2*28-19 = 39
To find the cost of a child's ticket, we can set up an expression based on the given information.
Let's call the cost of an adult's ticket "d" dollars.
According to the problem, the cost of a child's ticket is $19 less than twice the cost of an adult's ticket.
Twice the cost of an adult's ticket is 2d dollars.
Therefore, the cost of one child's ticket can be expressed as 2d - $19.
Given that an adult's ticket is $28, we can substitute this value into our expression for d.
So, the cost of a child's ticket is:
2(28) - $19 = $56 - $19 = $37.
Therefore, the cost of a child's ticket is $37.
To write an expression for the cost of one child's ticket, we need to find the cost in terms of the cost of an adult's ticket.
Let's call the cost of an adult's ticket as "d".
According to the given information, one child's ticket costs $19 less than twice the cost of an adult's ticket.
Twice the cost of an adult's ticket is 2d.
So, one child's ticket costs 2d - $19.
Now, we can simplify this expression further by substituting the value of "d".
Since an adult's ticket is $28, we substitute d = $28 into the expression.
The cost of a child's ticket = 2($28) - $19
= $56 - $19
= $37
Therefore, the cost of a child's ticket is $37.
2(28)-19
56-19
56+(-19)
37
