Answer:
zero dollars
Explanation:
Let's assume the guy's monthly allowance is "A" dollars.He donated 600 dollars, so his remaining allowance is (A - 600) dollars.He spent 1/3 of his remaining allowance on food, which is (1/3) * (A - 600) dollars.After spending on food, he is left with 1/2 of his allowance, which is (1/2) * (A - 600) dollars.Now, we can set up an equation:(1/2) * (A - 600) = ATo solve for "A," we'll first get rid of the fraction:A - 600 = 2ANow, isolate "A" on one side:A = 600So, the guy's monthly allowance is 600 dollars.Now, to find how much he spent on food:(1/3) * (600 - 600) = 0 dollarsThe guy spent 0 dollars on food.
