the total value of the money is $285. how many $10 notes are there?

There are 23 $10 notes and 11 $5 notes

Step-by-step explanation:

x= Number of$10 notes  

y=Number of$5 notes  

1x+1y=341  

Total value  

10x+5y=2852  

Eliminatey  

multiply (1)by-5  

Multiply (2) by1  

-5x-5y=-170  

10x+5y=285  

Add the two equations  

5x=115  

/5  

x=23  

plug value ofxin (1)  

1x+1y=34  

23+y=34  

y=34-23  

y=11  

y=11  

x=23Number of$10 notes  

y=11Number of$5 notes

5x+2x=49
