Write an equation and solve.

Question

A group of friends paid $7 each to play a round of golf. It also cost $12 to rent a golf cat. As a group, they paid $33 altogether. How many friends went to play golf?

Equation:
Answer

Answer 1

Let's denote the number of friends as \( x \).

The total amount they paid for playing golf can be expressed as:

• Each friend paid $7, so \( 7x \) represents the total amount paid by all friends.
• The cost to rent the golf cart is $12.

The total amount paid by the group is the sum of the amounts paid by the friends and the cost of the golf cart, which is given as $33. Thus, we can set up the equation:

\[ 7x + 12 = 33 \]

Now, we will solve for \( x \):

1. Subtract 12 from both sides:

\[ 7x = 33 - 12 \]

\[ 7x = 21 \]

2. Divide both sides by 7:

\[ x = \frac{21}{7} \]

\[ x = 3 \]

So, the number of friends who went to play golf is \( \boxed{3} \).
