The nerd that I am must provide the answer (17).
Or a Double Quarter-Pounder combo meal. Your choice.
60 isn't it? Burger (5) + fries (1), x drink (10), or do you have to do it another way round? I never know.
Good catch on the multiplication sign! I missed it. But, your answer is also incorrect.
Shakes are 10 each (10 + 10 + 10 = 30)
Burgers are 5 each (shake 10 + 5 + 5 = 20)
But fries are 2, not 1 (burger 5 + 2 + 2 = 9)
So burger plus fries times shake is (5 + 2 x 10), which looks at first like it would be 70 but, in math, the multiplication takes priority (unless there are parentheses), so it's 5 + (2 x 10) or 25.
