Option C
4 cups of sugar is needed
Solution:
Given that It takes 1/2 cups of sugar to make 3/8 gallons of sweet tea
cups of sugar =
![(1)/(2)](https://img.qammunity.org/2021/formulas/physics/middle-school/ukxexrkoplrwscaxd96qbbkphc5fo6w2ur.png)
gallons of sweet tea =
![(3)/(8)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/x2q5g60h9zz3zovzkcti6og4swfi4jks4o.png)
If the recipe is for 1 gallon of sweat tea, then the cups of sugar needed is given as:
![(3)/(8) \text{ gallons of sweet tea } = (1)/(2) \text{ cups of sugar }](https://img.qammunity.org/2021/formulas/mathematics/middle-school/jrzyte0qf8tapqw6gn7ve2d6eerefcan52.png)
![1 \text{ gallon of tea } = x \text{ cups of sugar }](https://img.qammunity.org/2021/formulas/mathematics/middle-school/6h19xuhjosam81o5spaglb858bcz7cehje.png)
On cross-multiplying we get,
![1 * (1)/(2) = x * (3)/(8)\\\\x = (1)/(2) * (8)/(3)\\\\x = (4)/(3)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/b3vhe5a7x7j3z7rz907gl24j4hdl73d9mi.png)
So to make triple the receipe, quantity of sugar needed is:
so the receipe is for 3 gallon of sweet tea, then sugar needed is:
![\rightarrow (4)/(3) * 3 = 4](https://img.qammunity.org/2021/formulas/mathematics/middle-school/l3ibt4z1l12wyswkztfbuyfqqrgij2spua.png)
Thus 4 cups of sugar is needed
