Taki and connor invest $20 in drink mix, sugar, and paper cups for a lemonade stand. after 5 hours they have made $50 in profits. assume that they sell the drinks at the same rate all day. write an equation for their profit for the day from the lemonade stand. if their stand continues to sell from 1: 00 p. m. to 8: 00 p. m. that day, what is their profit for the day?

They make 98 dollars in profits and the equation I dont know all i did is they spent 20 and made 50 in profits meaning they made 70 dollars and divided that by 5 since it said they did it in 5 hours then i got 14 the i did 14 times 7 because thats how much time is between 1 and 8pm hope that helped

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
