Answer 1

@Cardinal_Carlo

Answer 2

So, Joan paid $6 less for what was a $30 item. We just divide the difference by the total, and then multiply by 100:
\[p = \frac{ 6 }{ 30 } \times 100 = ~?\]
\[p = 20\]

Answer 3

what would you do if this problem was asking for increase? Would the equation the the same then? @Cardinal_Carlo

Answer 4

Yes. It would. Just remember:
\[p = \frac{ change }{ total } \times 100\]

Answer 5

ok
