Question

The student council at Deer Creek Middle School is organizing a dance to raise money for their
end-of-year trip. They want to raise at least $400. Tickets are priced at $4 each and they already spent
$25 on decorations. What is the minimum number of tickets they have to sell to reach their goal?

Answer 1

Answer:

The student council needs to sell a minimum number of 107 tickets to reach their goal.

Step-by-step explanation:

The student council needs to raise $400 with each ticket costing $4. As such, the number of tickets that need to be sold is

$400/$4 = 100

Easy, right?

But Hold On

The student council also spent $25 on decorations, so they need to make that back too. Thus, they need to sell an additional amount of tickets of

$25/$4 = 6.25

Since you can't sell 0.25 of a ticket though, round the answer up to 7.

So the overall total number of tickets that must be sold is 107.
