Question

The hot dog stand at the carnival makes 50c profit on each hot dog sold. If rental for the booth is $100. how many hot dogs must be sold to make a profit of at least $100?

Answer 1

You can constrict an equation for this where y is your profit and x is the number of hotdogs sold

Basically you start out with -$100 because you pay $100, then your earn 50 cents per hotdog so that means you can do .5x and that is your money from each hotdog sold

That means you get\[y=.5x-100\]
So if you input 100 for y(which is your profit) you get\[100=.5x-100\]If you solve for x you get your answer

Answer 2

so 400?

Answer 3

Yup well done
