In her science project, Martina observes how fast kitchen condiments can dissolve in water. She put 8.5 ounces of water into each of 5 containers. Complete the equation that models the total amount of water, w , Martina used.

The equation that models the total amount of water, w, Martina used is:

w = 8.5 * 5

where 8.5 represents the amount of water in each container, and 5 represents the number of containers.

To calculate the total amount of water that Martina used in her science project, we need to multiply the amount of water she put in each container by the number of containers. Since she put 8.5 ounces of water in each of the 5 containers, we can express this as an equation:

Total amount of water (w) = Amount of water per container × Number of containers

w = 8.5 ounces/container × 5 containers

Therefore, the equation that models the total amount of water Martina used is:

w = 42.5 ounces

To find the total amount of water, we need to multiply the amount of water in one container by the number of containers.

Given that Martina put 8.5 ounces of water into each of 5 containers, we can represent the amount of water in one container as 8.5 ounces.

To find the total amount of water, we multiply the amount of water in one container by the number of containers:

Total amount of water (w) = Amount of water in one container * Number of containers

w = 8.5 ounces/container * 5 containers

Thus, the equation that models the total amount of water Martina used is: w = 8.5 * 5.
