Question

Emmett's retirement party will cost $42 if he invites 7 guests. If there are 16 guests, how much will Emmett's retirement party cost? Assume the relationship is directly proportional.

Answer 1

$96.

We know these things:

The party costs $42 if there are 7 guests.

Put that into equation:

7x = 42

x = 6

Therefore:

16(6) = answer

16 x 6 = 96.

It will cost $96 to have Emmett's the retirement party.
