Answer 1

The cost of an order of large fries is
`\$ 2.10` and the cost of a hamburger is
`\$3.25`.

Explanation:

Let the cost of an order of large fries be
`\$ x`.

Then, the cost of a hamburger is
`\$ x+\$1.15`.

Bill bought two hamburgers and an order of large fries for a total of
`\$ 8.60`.

So,
`2(x+1.15)+x=8.60`

`\Rightarrow 2x+2.30+x=8.60`

`\Rightarrow 3x=8.60-2.30`

`\Rightarrow 3x=6.30`

`\Rightarrow x=(6.30)/(3)`

`\Rightarrow x=2.10`

So, the cost of an order of large fries is
`\$ 2.10`.

And, the cost of a hamburger is
`\$2.10+\$1.15=\$3.25`.

Hence, the cost of an order of large fries is
`\$ 2.10` and the cost of a hamburger is
`\$3.25`.
