Step 1: Determine the cost per attendee. Since the cost for 3 attendees is $12.90, divide $12.90 by 3.

$12.90 ÷ 3 = $4.30 per attendee.

Step 2: Determine the cost for 4 attendees. Since each attendee costs $4.30, multiply $4.30 by 4.

$4.30 x 4 = $17.20

So, if there are 4 attendees, Malia's graduation picnic will cost $17.20.
