Step by step evaluation:

$4times120 =$480 at $4 for each bowl. $3.5times140 =$490 at $3.5 for each bowl.

$3times160=$480 at $3 for each bowl. $2.5times180 = $450 at $2.5 for each bowl.

Maximum profit will be obtained at a price of $3.5. Check: What if one bowl is sold $3.75?

$3.75times130 =$487.5 It is lower than the maximum profit.
