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
