The number of bracelets that Sandra needs to sell in order to break even can be solved by equating the total cost to her total revenue. If the x represents the number of bracelets, the total cost would be, 2x + 15. Her total revenue from sales is expressed as 5x. Thus, the equation for breaking even is,
2x + 15 = 5x
2x + 15 = 5x
