#15For his science experiment, Julio placed a pan of water in his refrigerator to see how long it would take to evaporate. After 2 days, there were 280 ml of water in the pan, and after 4 days, there were 240 ml of water in the pan. In his report, he noted that the same amount of water evaporated each day. How many milliliters of water were in the pan to start?Enter your answer in the first response box. At this rate, how many days until no water remains in the pan?Enter your answer in the second response box.

The amount of water in the pan at start is 320 ml.

It takes 16 days until no water remains in the pan.

Step-by-step explanation:

Julio placed a pan of water in his refrigerator to see how long it would take to evaporate.

Let, the volume of water in the the pan during the start be 'x' milliliters.

After 2 days, he found that the water in the pan got reduced to 280 mlAfter 4 days, he found that the water in the pan got reduced to 240 ml.

Therefore, the difference in the volume of water within 2 days can be calculated using the given data.

The amount of water reduced in 2 days = volume of water remained after 2 days - volume of water remained after 4 days

⇒ 280 - 240 = 40 milliliters.

In can be determined that :

For 2 days the water gets evaporated by 40 milliliters.Thus, Each day 20 milliliters of the water gets evaporated from the pan.

To find the amount of water 'x' in the pan at start :

Before 2 days, the water in the pan is 40 milliliters greater than the water in the pan after 2 days.

The amount of water after 2 days is already given in the question itself which is 280 ml.

⇒ x = 280 + 40

⇒ x = 320 ml.

The amount of water in the pan at start is 320 ml.

To find the no. of days until no water remains in the pan :

The number of days at which all the water  gets evaporated is calculated by,

⇒ Total milliliters in the pan at start / No.of milliliters evaporated per day

⇒ 320 ml / 20 ml

⇒ 16 days.

It takes 16 days until no water remains in the pan.

Look at this and see if it
