Answer:

0.4 l of purple sand

Step-by-step explanation:

<u>Volume to be filled in:</u>

  • 2 liter = 2000 ml

<u>Red sand</u>

  • 1000 ml

<u>Blue sand</u>

  • 35 centiliters = 35*10 ml = 350 ml

<u>Yellow sand</u>

  • 2.5 deciliters = 2.5*100 ml = 250 ml

<u>Total volume filled:</u>

  • 1000 + 350 + 250 = 1600 ml

<u>Purple sand needed:</u>

  • 2000 - 1600 = 400 ml = 0.4 l

<u>Answer is</u> 0.4 l of purple sand required

Hello!

As we can see, our first amount was 95 for the one machine. We are not multiplying it by anything from the second day as it was used the first. There is no 95 in B, and in C and D it is multiplied.

In A, we have a base of 95, plus 25 multiplied by x and y, and this fits the scenario perfectly. Our answer is A.

I hope this helps!
