I need help with these 2 questions!

Joe and two friends are going to a concert. The total cost is $186. If there is a $24 service fee, write and solve an equation to find out how much one ticket is.

Four friends equally share the cost of their dinner that was $64 plus a 20% tip. If each person contributes $19, will that be enough to cover the bill with tip? Explain.

Respuesta :

#1: $186 ÷ 2 = $93 for each person without the fee.
#2: The 20% tip = $12.80

$64 + $12.80 =  $76.80

$19/per person = $19 × 4 = $76

No, it is not enough to cover the bill, with the tip included. Someone would have to pay 80 cents more. Hope this helps.
