Question

1. ellie is going to see a movie and is taking her 4 kids. each movie ticket costs $14 and there are an assortment of snacks available to purchase for $4.50 each. how much total money would ellie have to pay for her family if she were to buy 7 snacks for everybody to share? how much would ellie have to pay if she bought ( x ) snacks for everybody to share?

Explanation:

Step1: Calculate number of people

Ellie + 4 kids, so total people = \(1 + 4 = 5\)

Step2: Calculate cost of tickets

Each ticket is $14, for 5 people: \(5\times14 = 70\) dollars

Step3: Calculate cost of 7 snacks

Each snack is $4.50, 7 snacks: \(7\times4.50 = 31.5\) dollars

Step4: Total cost for 7 snacks

Ticket cost + snack cost: \(70 + 31.5 = 101.5\) dollars

Step5: General formula for \(x\) snacks

Ticket cost is still 70, snack cost for \(x\) snacks: \(4.50x\), so total cost \(C = 70 + 4.50x\)

Answer:

For 7 snacks, total cost is \(\$101.5\). For \(x\) snacks, total cost is \(70 + 4.50x\) dollars.
