Valentina's birthday party will cost $5.92 if she invites 4 guests. How many guests can there be, at most, if Valentina can afford to spend a total of $7.40 on her birthday party? Assume the relationship is directly proportional.

5 guests

Step-by-step explanation:

5.92 for 4 guests

= 7.40 for :

= 7.40/5.92 x 4

= 5

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
