Vernon Jewelry buys and sells jewelry. Its store policy is to buy necklaces for $60 and sell them for $125. Pairs of earrings are purchased for $35 and then sold for $65. Last week, the store had $3,305 in sales, which came to $1,635 in profit after accounting for the cost of the jewelry. Write an equation that describes the total sales for the week, and a second equation that describes last week’s profit.
