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

The clear answer is clearly 25 is very clear to me
