Shay and Nadine solve this problem in two different ways. You have $25 in your bank account. You make $7 per hour babysitting. How many hours must you babysit to have a total of $165 in your account? 

Respuesta :

Answer:

Number of hours to be babysit to have a total of $165 in the account = 20.7 hours

Step-by-step explanation:

Amount of money in the bank account = $25

Amount of money charged per hour for babysitting = $7

Let number of hours worked doing babysitting = x

Also, The total amount of money earned = $165

So, The equation which models the current situation is :

⇒ 25 + 7 × x = 165

⇒ 25 + 7·x = 165

⇒ 7·x = 165 - 25

⇒ 7·x = 145

⇒ x = 20.7

Therefore, Number of hours to be babysit to have a total of $165 in the account = 20.7 hours
