D) Eric was paid $458 last week. He was paid a $40 bonus and $11 for each hour he worked. What is h, the number of hours Eric worked last week?
The total amount he was paid is what the addends add up to, which is $458. This eliminates options A and B. Furthermore, it can't be C because it says "$40 for each hour he worked". In the equation, it says 11h, not 40h. The remaining option is option D.
