polet [3.4K]

Answer:

Step-by-step explanation:

We are given the following in the question:

Each brother purchase a new par of boots and two canteens.

Cost of one hiking boots = $34.00

Total cost of hiking boots =

=34\times 2\\=\$68.00

Let x dollars be the cost of one canteen.

Number of canteens bought by both brother = 4

Total bill = $98.00

Thus, we can write the equation:

68 + 4x = 98

Solving the equation, we get,

68 + 4x = 98\\4x = 98-68\\4x = 30\\x = 7.5

Thus, the cost of one canteen is $7.5
