Jin buys boxes of crackers that each has the same cost c. He represents the cost of 5 boxes of cheese crackers, 4 boxes of poppy seed crackers, and 3 boxes of plain crackers using the expression 5 c plus 4 c plus 3 c. What equivalent expression can represent the cost?

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

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
