Brenda pays $30 for materials to make earrings. She makes 10 earrings and sells 7 for $5 and 3 for $2. Write a numerical expression to represent this situation and then find Brenda's profit?
Brenda’s Profit is $11 This is because she spent $30 to begin with and made a total of $41, once the expenses for materials have been subtracted she is left with $11. 5x + 2y=41 x=7 (for the # of earrings sold for $5) y= 3 (for the # of earrings sold for $2) 5(7) + 2(3)=41 41 - 30 = 11
