Laptops are 1200 each and cameras are 500 each.
Using elimination:
3c+l=2700
5c+2l=4900
We will make the coefficients of l the same by multiplying the top equation by 2:
2(3c+l=2700)
6c+2l=5400
Our system is now
6c+2l=5400
5c+2l=4900
Subtract the bottom equation:
6c+2l=5400
-(5c+2l=4900)
We have
1c=500
So each camera is 500.
Substitute that in our original first equation:
3(500)+l=2700
1500+l=2700
1500+l-1500=2700-1500
l=1200

4.20+1.80=6.00
6.00 x .08 (8% tax)=.48 tax
6.00+ .48=6.48 total cost
10.00-6.48=3.52 change from a $10 bill
