Nancy sells handcrafted bracelets for $6. If her monthly fixed costs are $675 and each bracelet costs her $1.25 to make, how many bracelets must she sell in a month to make a profit?

Step-by-step explanation:

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

If her monthly fixed costs are $675 and each bracelet costs her $1.25 to make, it means that the total cost of making x bracelets would be

1.25x + 675

Nancy sells the handcrafted bracelets for $6. This means that the revenue she gets from selling x bracelets would be 6x

Profit = revenue - total cost

Therefore, to make profit, revenue must be greater than total cost. It means that

6x > 1.25x + 675

6x - 1.25x > 675

4.75x > 675

x > 675/4.75

x > 142.1

She must sell not less than 143 bracelets to make profit.
