Question

PLEASE HELP! :))
An artist makes three types of ceramic statues (large, medium, and small) at a monthly cost of $890 for 190 statues. The manufacturing costs for the three types are $6, $5, and $4. If the statues sell for $24, $16, and $13, respectively, how many of each type should be made to produce $3,060 in monthly revenue?

Answer 1

Let L, M and S be the number of large, medium and small statues respectively.
From the problem statement:
{ L + M + S = 190, 6 L + 5 M + 4 S = 890, 24 L + 16 M + 13 S = 3060 }
Solve the above for L, M and S .
{L = 40, M = 50, S = 100}
