Steven's favorite restaurant, The Peeled Onion, draws crowds for its famous onion rings. This week it is running a special for an order

of onion rings plus an old$-$school Italian soda fountain drink for just $$10.$ Normally, the onion rings sell for $$8\mathrm{.}40$ and the soda sells for

$$3\mathrm{.}60.$ Considering the primary revenue$-$generator is the order of onion rings, allocate the revenue to these two products using both

the stand$-$alone method and the incremental method, for internal decision$-$making purposes. $($Round percentage of total to $2$ decimal

places, e$.$g$.15\mathrm{.}25\%$ and final answers to $2$ decimal places, e$.$g$.15\mathrm{.}25.)$
