B because u have to do the math
total volume of the glass is
.
<u>Step-by-step explanation:</u>
Here we have , A glass is 1/4 full. Then 70cm3 of orange juice is poured in.
The glass is now 3/5 full. We need to find that What is the total volume of the glass . Let's find out :
Suppose that volume of glass is x ,so according to question we have the following equation
, Now, solve this to find value of x
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, total volume of the glass is
.
What are we trying to solve?
