Answer:

11s + 10l = 146

5s + 12l = 126

$8

Step-by-step explanation:

Let :

Small box = s

Large box = l

11s + 10l = 146 - - - - (1)

5s + 12l = 126 - - - - (2)

Multiply (1) by 5 ; (2) by 11

55s + 50l = 730

55s + 132l = 1386

Subtract

-82l = - 656

l = 8

11s + 10(8) = 146

11s + 80 = 146

11s = 66

s = $6

Hence, the price of a large box of tangerine = $8
