Atank contains 150 gal of fresh water. a solution containing 5lb/gal of soluble lawn fertilizer runs into the tank at the rate of 1 gal/minute, and the mixture is pumped out of the tank at a rate of 5 gal/min. find the maximum amount of fertilizer in the tank and the time required to reach the maximum

picture below

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
