In science class, Josh is mixing water and vegetable oil together. He has 275 milliliters of water. He has 70 fewer milliliters of oil than water. He pours both amounts into a large jar. How much liquid is in the jar in all?

Answer 1

To find the total amount of liquid in the jar, we first need to find out how much vegetable oil Josh has.

Since Josh has 275 milliliters of water and he has 70 milliliters less of oil than water, we can calculate the amount of oil as follows:

\[ \text{Amount of oil} = \text{Amount of water} - 70 \] \[ \text{Amount of oil} = 275 - 70 = 205 \text{ milliliters} \]

Now, we can find the total amount of liquid in the jar by adding the volume of water and the volume of oil together:

\[ \text{Total liquid} = \text{Amount of water} + \text{Amount of oil} \] \[ \text{Total liquid} = 275 + 205 = 480 \text{ milliliters} \]

Therefore, the total amount of liquid in the jar is 480 milliliters.
