Suzy is starting a babysitting buisness. She spent $ 36 to make signs to advertise. She charges and intial fee of $ 6 and then $ 3 for each hour of service. Write and solve an inequality to find the number of hours she will have to babysit to make a profit.
1 answer:
Answer:
3h - 30 > 0
h > 10
Step-by-step explanation:
To make a profit, subtract $36 in cost from the income coming in.
She charges $6 and then $3 per hour or 3h. Her income coming in is 6 + 3h.
Subtract 36 from it to find the profit.
3h + 6 - 36
3h - 30
To make a profit, she needs to make more than $0 or > 0.
3h - 30 > 0
Solve using inverse operations.
3h - 30 > 0
3h > 30
h > 10
