A company orders 8 boxed lunches from a deli for $99.60. If each boxed lunch costs the same amount, how much do 26 boxed lunches cost?

The cost per boxed lunch is $99.60 / 8 = $<<9960/8=12.45>>12.45.

The cost of 26 boxed lunches is $12.45 * 26 = $<<12.45*26=323.70>>323.70. Answer: \boxed{323.70}.
