To solve this problem, we need to determine the value of x, which represents the cost of each cup of milk tea.
Let's break down the information given:
Cost of each movie ticket: $7
Number of movie tickets: 3
Cost of each box of popcorn: $1.5
Number of boxes of popcorn: 2
Cost of each cup of milk tea: $x
Number of cups of milk tea: 3
Total contribution per person: $11
We can set up the equation as follows:
(Cost per movie ticket * Number of movie tickets + Cost per box of popcorn * Number of boxes of popcorn + Cost per cup of milk tea * Number of cups of milk tea) / Number of friends = Total contribution per person
($7 * 3 + $1.5 * 2 + $x * 3) / 3 = $11
Let's simplify and solve for x:
($21 + $3 + $3x) / 3 = $11
($24 + $3x) / 3 = $11
To isolate x, we multiply both sides of the equation by 3:
3 * ($24 + $3x) / 3 = $11 * 3
$24 + $3x = $33
To isolate x, we subtract $24 from both sides of the equation:
$24 + $3x - $24 = $33 - $24
$3x = $9
To solve for x, we divide both sides of the equation by $3:
$3x / $3 = $9 / $3
x = $3
The value of x is $3.
#### 3
The answer is: 3
