Question

Equation: t = 25 + 8.25w Aaliyah needs $135.75 for a television. How many weeks will it take her to save enough money to buy a television?

Answer 1

Answer: 14 weeks

Explanation:

The given equation :
`t=25+8.25w`, where w represents the number of weeks.

Aaliyah needs $135.75 for a television.

To find the number of weeks (w) will it take her to save enough money to buy a television , we put t=135.75 in the above equation we get

`135.75=25+8.25w\\\\\Rightarrow\ 8.25w=135.75-25\\\\\Rightarrow\ 8.25 w=110.75\\\\\Rightarrow\ w=(110.75)/(8.25)=13.4242424242\approx14`

Hence, it will take 14 weeks to save enough money to buy a television.
