Astudent makes and sells braclets at craft show . the material to make each bracelets cost is 7.50 the braclets each cell 32.50 each the booth at the craft show costs 255 how many braclets do the students sell to break even ? what is the break even point?

the break even point is when 10 bracelets are made and sold.

Step-by-step explanation:

Let x represent the number of bracelets that the student makes and sells.

The material to make each bracelets cost is 7.50. This means that the cost of making x bracelets would be

x × 7.5 = 7.5x

The the booth at the craft show costs 255. This means that the total cost incurred would be

7x + 255

The cost of selling each bracelet is 32.50. It means that the total cost of selling x bracelets would be

32.5 × x = 32.5x

At the point of break even, profit is zero. Therefore

Revenue - cost = 0

Revenue = cost

So

32.5x = 7x + 255

32.5x - 7x = 255

25.5x = 255

x = 255/25.5

x = 10

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
