For each handmade greeting card jacqui sells, she makes a profit of $0.35. in one week, she made a profit of $42. she sell the cards for $0.75 each.
a. about how many greeting cards did jacqui sell that week ?
b. about how much did she earn before paying expenses ?

To work out the number of cards sold, divide the total profit made for the week by the profit made on each card. 42/0.35 = 120. Jacqui sold 120 cards. Then to work out how much she earned before expenses (t), add her profit to the price of each card x how many cards were sold. T = 42 + (120 x 0.75). T = 42 + 09. T = 132. She earned $132 before expenses.
