Pls . a jar contains 0.85 liter of strawberry jut and 0.50 liter mango juice. celina poured 0.15 liter of watermelon juice into the jar. she then drank 0.30 liter of the mixture part a: write an expression to represent the total amount of juice left in the jar. part b: identify which property is used in each step to simplify the expression.

Part A:  .85 + .50+ .15= 1.50

1.50 - .30= 1.20   liters left

Part B: I used the Substitution property because we knew how much juice was in the jar and we knew how much she drank But we did not know how much was left in the jar which we used the substitution property to figure out how much was left in the jar after she drank .30 liters.
