Question

Your food costs are $1700. Your total food sales are $2890. What percent of your food sales do the food costs represents?

What I think: 58.82

Answer 1

I agree with you, and since you got the right answer, you would know why.
1700/2890 ≈ 0.5882 = 58.82%

However, usually, you should write about 58.82% as it isn't exactly 58.82
