You make cards and sell them for $2.50 each. It costs $1.15 to print each card. You also pay $50 for supplies. How many cards must you sell to meet the cost for making the cards (you break even)? Round up to the next whole card.

A. 20 cards
B. 37 cards
C. 20.46 cards
D. 38 cards

D. 38

50 + 1.15x = 2.50x

Solve for x.

the answer is 38

You rent a small 2 bedroom house. You paid a $600 deposit the day you moved in so your rent is only $250 each month. Since your roommate did not pay any of the deposit, her rent is $400 each month. In how many months will you and your roommate have spent the same amount?

To find the number of cards you need to sell in order to break even, you need to account for both the printing cost per card and the supplies cost.

Let's break it down:
- The cost to print each card is $1.15.
- The cost of supplies is $50.

To find the number of cards needed to break even, we can set up an equation:

Total Cost = Total Sales Revenue

The Total Cost is the sum of the printing cost per card and the supplies cost:
Total Cost = $1.15 * Number of Cards + $50

The Total Sales Revenue is the product of the price per card and the number of cards:
Total Sales Revenue = $2.50 * Number of Cards

Now let's set up the equation:
$1.15 * Number of Cards + $50 = $2.50 * Number of Cards

To find the number of cards needed to break even, we'll isolate the Number of Cards term:
$50 = $1.35 * Number of Cards

Divide both sides of the equation by $1.35:
Number of Cards = $50 / $1.35

Approximating the value, we find:
Number of Cards ≈ 37.04

Since you can't sell a fraction of a card, you need to round up to the next whole card.

Therefore, you need to sell 38 cards to meet the cost for making the cards. Thus, the answer is D. 38 cards.
