a. p = 8n - 30 Each item n is $8. Expenses totaling $30 are subtracted. So if the profit (p) is $170.00, 170 = 8n - 30 Now you need to solve. Add 30 to both sides. 200 = 8n Divide both sides by 8. 25 = n 25 items were bought. b. If 25 items were bought, but the expenses were instead $40, what would be the total profit? p = 8(25) - 40 p = 200 - 40 p = 160 The profit decreased by 10.
