Question

Rosa is saving money to buy a baseball bat that costs $229. Rosa has$19 and will save $14 each week. How many weeks will it take Rosato save enough money to buy the baseball bat? Write an equation torepresent this situation. Do not simplify the equation. Use w torepresent the number of weeks.

Answer 1

Let w be the number of weeks that Rosa have to work to save enough money. Since she can save 14 dollars per week, and that she started saving money with 19 dollars, then the equation would look like this:

`14w+19=229`

Solving for w we get:

`\begin{gathered} 14w+19=229 \\ \Rightarrow14w=229-19=220 \\ \Rightarrow w=(220)/(14)=15 \end{gathered}`

Therefore, Rosa has to work 15 weeks to save enough money to buy the baseball bat.
