Wayne earned a total of $8 by selling 4 cups of lemonade. After selling a total of 5 cups of lemonade, how much money will Wayne have made in all? Solve using unit rates.

$10

Step-by-step explanation:

Unit rate

$8/4cup = $2/cup

Therefor

5 cups * $2/cup = $10

18$

Step-by-step explanation:first you wanna see the rate 8 dollars for 4 cups so 8/4 gives you 2.The rate is 2 dollars per cup.

So now we have to find how much 5 cups is worth.Since we know how much each lemonade cost we just have to plug it all in!So 5*2.Is 10 and we also made 8 bucks from the first 4 cups.

Now that we know that we sold 8$ the first time and 10$ the second we add them all up to give you “18$“total

x = 3 ± √(5+y)
