Question

Gavin needs $80 to buy a fish tank. He has saved $8 and plans to work as a babysitter to

earn $9 per hour. Which inequality shows the minimum number of hours, n, that Gavin
should work as a babysitter to earn enough to buy the fish tank?

Answer 1

so the answer would be 8+9n≥80. The reason why is because he has $80 and he saved $8 and he earned $9 for each hour but we do not know how many hours so that is why it is n. and it says minimum so u might think that it might be ≤ but my sister says to think the opposite so the symbol will be ≥.
