Let burgers be b and hotdogs be h. 2b+2h= \$15.56 and 3b+5h= \$29.92

Solving the system of equations, we get b+h= \$7.78 which means that 3b+3h= \$23.34...we subtract this from the second equation and get

3b+5h-(3b+3h)= \$29.92- \$23.34

2h= \$6.58

Dividing by 2 we get hotdogs to cost \$3.29

If we have this cost then we can find the cost of burgers by doing b+ \$3.29= \$7.78

Solving for b we get b= \$4.49 so burgers cost \$4.49.

Hope it helps!
