The cost of a pack of chewing gum in a vending machine is $0.75. The cost of a bottle of juice in the same machine is $1.25. Julia has $22 to spend on chewing gum and bottles of juice for her team and she must buy seven packs of chewing gum. If b represents the number of bottles of juice, which inequality represents the maximum number of bottles she can buy?

You did not give the options.
the inequality would be
22> .75 (7) + 1.25 (b)
-

this simplifies to 22 > 5.25 + 1.25(b)
-

You subtract 5.25 from both sides to get

16.75>1.25b
_

Divide both sides by 1.25 to get b by itself
to get

13.4> b
_

This means that she can buy at most 13 bottles because you cannot buy part of a bottle

So the equation is 13>b
-
The number of bottles she can buy is at most 13

P.S Dash under greater than sign it won't let me type it
