Question

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 ?

Answer 1

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.

Answer 2

The correct answers are:

A) 120 cards; and

B) $90.

Explanation:

Let x be the number of greeting cards sold that week. She earns $0.35 per card and earned $42; this gives us the equation

0.35x = 42

Divide both sides by 0.35:

0.35x/0.35 = 42/0.35

x = 120

She sold 120 cards.

She sells each card for $0.75. This means she earned

0.75(120) = $90.
