Answer:
5400
Step-by-step explanation:
Let x represent the cost of a chair and y represent the cost of a table. We can use this to set up a system of equations:
7x=2y
6x+5y=10575
We can solve this system using substitution.
Start by rewriting the first equation in terms of x.
Substitute this into the second equation:
Multiply both sides by 7
Divide both sides by 47
This means...
Divide both sides by 7
One chair costs 450. Now, multiply this number by 12 to find the cost of 12 chairs.
12 chairs cost 5400.
