Write a System of Equations to Describe the Problem Situation $y = 5 x , 10 x + 25 y = 450$

Write a system of equations to describe the problem situation. It is not necessary to solve the problem. Restaurants buy 10-pound and 25-pound bags of carrots. They want five times as many 10-pound bags (x) as 25-pound bags (y) . If the company estimates that restaurants will buy 450 pounds of carrots, how many bags of each size should be packaged?

A) $y = 5 x , 10 x + 25 y = 450$
B) $x = 5 y , 10 y - 25 x = 450$
C) $x = 5 y , x + y = 450$
D) $y = 5 x , x + y = 450$
E) $x = 5 y , 10 x + 25 y = 450$
