Given parameters:
Rate;
2 cans of paint for 7 dollars
Number of cans of paints = 9 cans
Unknown:
Cost of 9 cans of paints = ?
This is rate - work problem. So therefore, we can simply solve them;
Since;
2 cans of paint costs 7 dollars
9 cans of paint will now cost [tex]\frac{9 cans x 7 dollars}{2 cans}[/tex] = $31.5
The cost of 9 cans of paint is $31.5
