Paula purchased adult and child tickets for the carnival. tickets cost $19.95 for each adult and $9.95 for each child. let x represent the number of adult tickets purchased and y represent the number of child tickets purchased. write an expression to represent the total cost of the tickets paula purchased.
$19.95x + $9.95y
$19.95y + $9.95x
($19.95 + $9.95)(x + y)
($19.95 - $9.95)(x + y)

A: $ 19,95 + $9,95

Step-by-step explanation:

Cost of adult ticket: $19,95

Cost of child ticket: 9,95

x: number of adult tickets

y: number of child tickets

$19,95x + 9,95y =  T,total cost of tickets paula purchased.

For example, if there were 4 adults and 3 children,

($19,95 . 4) + ($9,95 . 3)= T

$79,80 + 29,85= 109,65

the total cost of tickets would be $109,65.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
