nicole charges a flat fee of $3 to babysit, as well as $4 per hour. She earned $15 on Friday night. How many hours did she work?
2 answers:
Answer: 3 hours
Step-by-step explanation: Subtract the flat fee first. 15-3=12. She earned $12 without the flat fee, so divide that by 4. $12/$4 per hour = 3 hours.
Answer:
3 hours
Step-by-step explanation:
Number of hours worked = x
Write an equation
$3 + 4x = $15
Subtract $3 from both sides
4x = $12
Divide both sides by 4
x = 3
