Answer 1

To determine who has the strongest drink, calculate the concentration of each drink. Sophia has a concentration of 0.28, while Tommy has a concentration of 0.25. Therefore, Sophia has the strongest drink.

Step-by-step explanation:

To determine who has the strongest drink, we can compare the concentration of each drink. The concentration of a drink is determined by the amount of concentrate mixed with a certain volume of water.

For Sophia's drink, the concentration can be calculated as follows:

Concentration = Amount of Concentrate / Total Volume of Drink

Concentration = 70ml / (70ml + 180ml)

Concentration = 70ml / 250ml

Concentration = 0.28

For Tommy's drink, the concentration can be calculated as follows:

Concentration = Amount of Concentrate / Total Volume of Drink

Concentration = 90ml / (90ml + 270ml)

Concentration = 90ml / 360ml

Concentration = 0.25

Since Sophia's drink has a higher concentration (0.28) compared to Tommy's drink (0.25), Sophia has the strongest drink.
