Answer:
The correct answer is $90.
Step-by-step explanation:
First we must start by analyzing the information we have.
We know Tammy has 144 guests in total. You can put 8 guests per table, for each table she will spend $ 5.
Now we must find out how much she will spend in total to be able to pay for all the guests.
If 8 guests ------ $ 5
144 guests ---- x
With this information we can do a cross-multiplication:
8x=144.5
8x = 720
x = 720: 8
x = 90
In this way we verify that Tammy will spend $ 90 to rent the tables.
