Two brothers each purchase a new pair of hiking boots and two canteens. The hiking

boots cost $34.00 each. The total of their purchase was $98.00.

a. Define a variable:

b. Write an equation:

c. Solve:

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
