Which of the following is not an inequality? A
435 ≥ 5p + 4
B
g - 7 < 100
C
18x + 9y
D
a > 6b

A.

= 435 > 5p + 4
= 435 - 4 > 5p + 4 - 4 (what u do to one side you do to the other)
= 431/5 > 5p/5
= 86.2 > p ✅

I can tell you A is in fact an inequality but everything else i didn’t understand what you were trying to say with the & and stuff :/

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425

If you make you answer for clear i can answer it : )
