Studdy Solution

STEP 1

What is this asking? How many guests can Ernest invite to his birthday party if it costs $60\$60 for 4 guests and he has $315\$315 to spend? Watch out! Don't mix up the cost per guest and the number of guests!

STEP 2

1. Calculate the cost per guest
2. Determine the maximum number of guests

STEP 3

Alright party people, let's break down the cost!
We know Ernest's party costs $60\$60 for 4 guests.
We want to find the cost *per* guest, so we'll **divide** the **total cost** by the **number of guests**.
Dividing by 4 guests gives us a **cost per guest** of $604=$15\$\frac{60}{4} = \$15.
Fifteen bucks a head!

STEP 4

Now, Ernest has a whopping $315\$315 burning a hole in his pocket.
We know each guest costs $15\$15, and we want to see how many guests he can afford.
To do this, we'll **divide** his **total budget** by the **cost per guest**.

STEP 5

So, we have $31515\$\frac{315}{15} which gives us... *drumroll please*... **21 guests**!

STEP 6

Ernest can invite at most **21 guests** to his awesome birthday bash!
