Question

The corporate team-building event will cost $12 if it has 3 attendees. If there are 4 attendees, how much will the corporate team-building event cost? Assume the relationship is directly proportional.

Answer 1

step 1

Find out the unit rate

Divide the total cost by the number of attendees

so

12/3=$4 per attendees

If we have 4 attendees

then

Multiply the unit rate by 4

4*4=$16

the answer is $16
