Ms. Gray is going to save money until she can afford to buy a new television that costs $4,189 including tax if she saves $60 each month which is the best estimate of the number of months it will take her to save

Respuesta :

Let n be the number of months Ms. Gray will need to save $4,189, then we can set the following equation:

[tex]4,189=60n\text{.}[/tex]

Dividing the above equation by 60 we get:

[tex]\begin{gathered} \frac{4189}{60}=n, \\ n\approx69.82. \end{gathered}[/tex]

Since n must be a whole number, then Ms. Gray needs at least 70 months to save enough to buy a new television.

Answer: 70 months.
