write an equation and solve. Jennifer is saving money to buy a bike. The bike costs $245,and each week she add $15 to her savings. How long will it take her to save enough money to buy the bike?

Respuesta :

We know that

• The bike costs $245.

,

• Jennifer adds $15 per week to her savings.

Let's call w weeks. Based on the given information, we express the following.

[tex]\begin{gathered} 15w=245 \\ w=\frac{245}{15} \\ w=16.3333\ldots \end{gathered}[/tex]

It will take 17 weeks to save enough money to buy that bike.

Notice that we can't say 16 weeks, otherwise, the money wouldn't be enough to buy it.
