Can someone answer this question please?

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 = [tex]\frac{5}{8}[/tex] y
iv) therefore x + y = 1235 milliliters
v) therefore [tex]\frac{5}{8}[/tex] y + y = [tex]\frac{13}{8}[/tex]y = 1235 [tex]\Rightarrow[/tex] 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.
