Question 1111708
Car I	x	gallons	for the for the week									
Car II	y	gallons	for the for the week									
Equation for tickets	total distance											
												
1	x	+	1	y	=	35	.............1					
												
Equation for amount spent												
15	x	+	35	y	=	825	.............2					
Eliminate y												
multiply (1)by		-35.00										
Multiply (2) by		1										
-35.00	x		-35.00	y	=	-1225.00						
15.00			35.00	y	=	825.00						
Add the two equations												
-20.00	x				=	-400.00						
/	-20.00											
x	=	20.00										
plug value of			x	in (1)								
1.00	x	+	1.00	y	=	35.00						
20.00		+	1.00	y	=	35.00						
			1.00	y	=	15.00						
				y=		15.00						
												
Car I	20.00	gallons	for the for the week									
Car II	15.00	gallons	for the for the week
