If 5 burgers and 4 orders of fries cost $30.76 and 8 burgers and 6 orders of fries cost $48.28, what is the cost of a burger and what is the cost of an order of fries?

Step-by-step explanation:

5B+4F= $30.76

×3

15B+12F= $92.28

8B+6F= $48.28

×2

16B+12F= $96.56

Cost of one burger:

$97.56-$92.28= $4.28 (final ans)

Cost of one fries:

$30.76-5($4.28)= $9.36 (for 5 fries)

$9.36÷5= $1.87 (final ans)
