A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for ever

Sphinxa [80]

Answer:

$304\dfrac{4}{7}\ milliliters$

Step-by-step explanation:

If there are 3 milliliters of compound A used for every 4 milliliters of compound B, then we can denote that we use 3x milliliters of compound A and 4x milliliters of compound B to get 533 milliliters of the drug. Thus,

$3x+4x=533,\\ \\7x=533,\\ \\x=\dfrac{533}{7}\ milliliters.$

Hence, a chemist must take

$4\cdot \dfrac{533}{7}=\dfrac{2132}{7}=304\dfrac{4}{7}\ milliliters$

of compound B.
