The equation we can generate from this is:
P = 0.35 x
where P is profit, and x is the number of cards made
A. when P = 42
42 = 0.35 x
x = 42 / 0.35
x = 120 cards
Therefore Jacqui sold 120 cards that week
B. To find for the total earning before expenses:
total earning = $42 + $0.75 * 120
total earning = $132
To find the answer for how many cards were sold take the amount per card that she made a profit on which is $.35 multiply that by the amount she profited in one week which is $42. $.35 x $42 equals 120 cards sold.
Now that we know how many cards she sold, take that number (120 cards) and multiply is by the amount each card was sold for ($.75). 120 x $.75, which equals $90 all together before paying expenses.
