Answer:
Sale Price per Unit:
Card Games = $6.00
Puzzles = $15.00
Variable Costs per Unit:
Card Games = $2.00
Puzzles = $3.50
Products sold ratio (3:2)
Total Fixed Costs: $24,500
Profit = Selling Price of each product - Cost Price of each product - Fixed Price
if SC & SP are the sold quantities of Card Games & Puzzles respectively then,
Profit = (6 x SC) + (15 x SP) - (2 x SC) - (3.5 x SP) - 24,500
Taking Profit = 0 to calculate break-even,
0 = SC (6-2) + SP (15-3.5) -24,500
According to the given ratio:

Substituting the value of SC in terms of SP to above equation:
0 = (3/2)SP (6-2) + SP (15-3.5) -24,500
24,500 = (3/2)SP (4) + SP (11.5)
24,500 = SP(6 +11.5)
(24,500/17.5) = SP
SP = 1400
1,400 Puzzles need to be Sold in order for the company to break-even.
