Answer:
$4 for each person
Step-by-step explanation:
First we have to calculate how much money has money other than for food
for this we multiply the number of guests by the value of each dinner
$8 * 10 = $80
Now that we have the total value of the dinner we substract from the total money
$120 - $80 = $40
This is the mount that she can spend on party favors
Then we split the $40 with the total number of guests to know how much we can spend for each person
$40/10 = $4
