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 sells the cards for $0.75 each.

Part A: About how much did she earn before paying expenses?

Answer 1

 earn before paying expenses  <---- Revenue = price * quantity

so, how many did she sell?  well, we know she makes a profit of 0.35 for each, and in that week, she made a total profit of 42 bucks, so she sold 42/0.35 or 120 greeting cards.

quantity = 120
price     = 0.35

Revenue = price * quantity.  <---- that's how much she earned before expenses.

Answer 2

Answer:

$ 90

Step-by-step explanation:

Given,

The profit in each card = $ 0.35,

If she sold x cards,

Then the total profit she earned = profit in each card × number of cards

= 0.35x dollars,

According to the question,

0.35x = 42

$\implies x = \frac{42}{0.35}=120$

Thus, she sold 120 cards,

Now, if the selling price of each card = $ 0.75,

Hence, total earning before paying expenses

= selling price of each card × total cards

= 0.75 × 120 = $ 90
