Help. teach me how to solve ameircan math

value of hamburger without cheese is undefined. Infinite solutions exist

HUEHUEHEUE so funny , huh.

Except that's wrong dipshit.

KNOWN:

Milkshake = s
Burger = b
Fries = f

SOLN:

=> 3M = 30, so M = 10
=> 10 + 2b = 10, so b = 5
=> 5 + 2f = 9, so f = 2

(5)+(2*10) = 25

you guys are dumb obviously the correct answer is obesity because its fast food

This.

Soda = 10 shillings
Burger (whole) = 5 shillings
Two fries = 2 shillings
_______________________________

The burger has 6 elements, 2 buns, 2 beef patties, cheese and w/e brown shit.
Each element costs 0.83 shillings, just 5/6. Now that there is 5 elements left, 0.83x5 = 4.16 rounded to 4.2 shillings.

4.2 + 1 x 10 = 14.2 shillings.

Though the most obvious answer is to return the burger to get it for free, then it all comes costs 10 shillings. You get the fries for free because fuck it.
