Set up and solve equations for the following business situations.
You are planning to advertise your boat for sale on the Internet. The Boat Mart charges $1.30 for a photo plus $0.12 per word. Boat Bargains charges $1.80 for a photo plus $0.10 per word. For what number of words will the charges be the same?
To calculate: The number of words for those the same charge will be paid, if for advertising the Boat Mart charges

Step4: Solve the equation by rearrange the unknown values to the left side and known values to the right side of the equal sign.
Step5: Prove the solution by substituting the value obtained from step 4 in the equation formed in step 4 then check the left and right of the equation if, they are equal then the answer is correct.
Calculation:
Underline the keyword by using the table of key word.
The price of photo plus price per words multiply by the number of words equals total paid amount.
Suppose that X be the number of words for those the same charge will be paid.
Consider the Boat Mart charges
Consider the charge paid,
Now solve the equation
