Last month, a certain manufacturer sold a total of 1,000 units of its two products, A and B. The selling price of each unit of product A was $1,500, and the selling price of each unit of product B was $2,000. How many units of product A did the manufacturer sell last month?

1) Last month, the manufacturer's total revenue from the sale of units of products A and B was $ 1,600,000.
2) Last month, the manufacturer's total revenue from the sale products A was 3 times the manufacturer's revenue from the sale of units of product B.

convert each into an equation, if number of products of A is a and of B is b..

Quote:
a certain manufacturer sold a total of 1,000 units of its two products, A and B.

\(a+b=1000\).....(i)

1) Last month, the manufacturer's total revenue from the sale of units of products A and B was $ 1,600,000.
price of a and b is given..
so \(1500a+2000b = 1600000\).....(ii)
TWO equations i and ii, TWO variables a and b...Can be solved
suff

2) Last month, the manufacturer's total revenue from the sale products A was 3 times the manufacturer's revenue from the sale of units of product B
so \(1500a = 2000b\)
again TWO equations i and ii, TWO variables a and b...Can be solved
suff
