Question 534358
let  number of bowls be x
and plates be y

time taken 
3x+2y= 480  

Money spent
0.25x+0.2y = 44
multiply by 100 to eliminate the decimals
25x+20y=4400

bowls	x	numbers	,	Price =		$3.00		
plates	y	numbers	,	Price =		$9.00		
				Total		345		
3	x	+	2	y	=	480	.............1	
25	x	+	20	y	=	4400	.............2	
Eliminate y								
multiply (1)by 		-10						
Multiply (2) by		1						
-30	x		-20	y	=	-4800		
25	x		20	y	=	4400		
Add the two equations								
-5	x				=	-400		
/	-5							
x	=	80						
plug value of 			x	in (1)				
3	x	+	2	y	=	480		
240		+	2	y	=	480		
			2	y	=	480		-240
			2	y	=	240		
				y	=	120		
bowls	80	numbers						
plates	120	numbers
