The other friend brings his own bowling shoes, bowls 4 games, and buys a soda for \)0.50. Both friends spend the same amount of money.

Short Answer

Expert verified

The equation is 7x=$3.50 and the cost of one game is $0.50.

Step by step solution

01

Step 1.  Apply the concept of Linear equation

In this type of question, use the concept of making a linear equation and do various mathematical operations

02

Step 2.  Finding the equation of the situation

Since, one friend rents a pair of bowling shoes for $3 and other friends buys a soda for $0.50.

Now,

Number of games played = 4+3=7

So, let the cost of one game be x.

Cost of 7 games = 7x

Total money spent by both the friends = $0.50+$3=$3.50(on\adding)

So, the equation for the situation becomes,

7x=$3.50

03

Step 3.  Solving the equation to get x

The equation is 7x=$3.50

Simply, divide to both side of the equation

7x=$3.507x7=$3.507x=$0.50
