Answer: 2(34) + 2c = 98
Step-by-step explanation:
C = cost of one canteen
2 pair of boots at $ 34 each plus 2 canteens at (c) each totals $98.
2(34) + 2c = 98
68 +2c = 98. Subtract 68 from both sides. 68 - 68 +2c = 98 -68
2c = 30. Divide both sides by 2.
2c/2 = 30/2
c = 15 so each canteen costs $15
Check: 2 ($34) + 2 ($15) = $98
$68 + $30 = $98
$98 = $98
2C = 98
