28x+86≤200 because for supplies they divide the rest of money. that means, 200-28=172 so 172/2=86 now we gonna find the value of x. 28x+86≤200 i am gonna subtract 86 both of side 28x+86-86≤200-86 to get value of x. 28x≤114 divide 28 both of side to get value of x so it will be x≤4
Use PEMDAS. So it would then simplify to [100+(586+4)]/5<19 then continueing that it would be [100+590]/5<19 and then 690/5<19 which finally will be 138<19 and that is a valid statement
