Question

Can someone gice me the correct answer please.

Answer 1

Answer:

A. f: the number of friends attending Alisa's party.

Step-by-step explanation:

We know that it takes Alisa 10 minutes to full a dozen balloons, and if each of her friends gets one dozen balloons, and if $f$ is the number of friends, then the total dozens of balloons will be   $f$ (because each friend gets a dozen balloons.)

Thus we must know $f$: the number of friends attending Alisa's party, if we are calculate the time Alisa will take to fill all the balloons.
