Answer 1

how is choice D. ? please repost it clearly

Answer 2

"$5.90 per hour"
the first hour, he earns $5.90
the second hour, he earns 2*5.90, and so on.

so clearly, the amount he earns is 5.90*(number of hours)

since he wants at least $236, set the quantity 5.90*(number of hours) greater than 236 with the appropriate inequality symbol
