Answer:
Therefore we need 475 milliliter of Compound A
and we need 760 milliliter of compound B.
Step-by-step explanation:
i) let x be the number of milliliters of compound A
ii) let y be the number of milliliters of compound B
iii) It is also given that x = y
iv) therefore x + y = 1235 milliliters
v) therefore y + y = y = 1235 y = 760 milliliter
vi) therefore x = 1235 - 760 = 475 milliliter
Therefore we need 475 milliliter of Compound A
and we need 760 milliliter of compound B.
