Question

Write an equation and solve.

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?

Answer 1

Let's let \( x \) represent the number of friends who went to play golf. Each friend paid $7, so the total amount contributed by all friends is \( 7x \). Additionally, the group paid $12 to rent a golf cart.

According to the problem, the total cost for the group was $33. We can set up the equation as follows:

\[
7x + 12 = 33
\]

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

1. Subtract 12 from both sides of the equation:

\[
7x = 33 - 12
\]
\[
7x = 21
\]

2. Divide both sides by 7:

\[
x = \frac{21}{7}
\]
\[
x = 3
\]

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