An artist makes three types of ceramic statues at a monthly cost of $650 for 180 statues. the manufacturing costs for the three types are $5,$4, and $3. if the statues sell for $20,$12, and $9,respectively, how many of each type should be made to produce $2,100 in monthly revenue?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
