Which inequality could be used find the number of hours Sophia needs to work to make enough money to buy a new bicycle?

$8.22h > $623
$8.22h ≤ $623
$8.22h ≥ $623
$8.22h < $623

Answer 1

Can she buy a bicycle with less that $623?

Answer 2

Answer 10

ok, thanks.

Answer 11

We know that x cannot be negative because two negative numbers would make a positive number, and we want -10

We also know that x cannot be less that five because we need it to equal -10 or lower.

Answer 12

ok. thank you.
