Parentheses first. So (2+3) = 5. Then (5)×2 = 10. 22 is already over 10, and you're adding to that so that would make it false

gregori [183]

Answer/Step-by-step explanation:

Let x = 4 (you and 3 friends)

Ticket cost per head = $5.50

Drink cost per head = $2.50

Popcorn cost per head = $4.00

<em>Expression representing total amount of money spent = $5.50(x) + $2.50(x) + $4.00(x)</em>

<em />

Evaluate the expression by plugging in the value of x = 4

Total amount of money spent = $5.50(4) + $2.50(4) + $4.00(4)

= $22 + $10 + $16 = $48

<em>Total amount of money spent = $48</em>
