Help!!! My grade is so low!!
Carla earns $6.25 per hour working at a store. When she gets her paycheck she repays her brother $40. She has at least $120 left over. Rounding to the nearest hour, which is the minimum number of hours Carla worked?

Respuesta :

Let x = hours Carla worked

6.25x - 40 ≤ 120
+40 +40
—————————
6.25x ≤ 160
——— ——
6.25 6.25
—————————
x ≤ 25 hours

I’m not sure if this is right, but I’m kinda positive about it. Hope it helps! :]
