either 449/25 or 11/25 depends on the -14/5 or
Step-by-step explanation:

if it the first one then the answer should be 449/25 but if ut the second one it should be 11/25 .
u just substitute the -14/5 to x then solve
4500 + 1.20x < 4.80x
4500 < 4.80x - 1.20x
4500 < 3.60x
4500/3.60 < x
1250 < x.......minimum number would be 1251
