1. ana was washing dishes at the end of her shift at a restaurant. she washed 30 plates from 7: 30 to 7: 35. when she finishes washing all the plates, her shift will end. (a) if she started washing plates at 7: 15 and ended at 7: 38, estimate how many plates she washed in total. explain your reasoning. (b) write an equation to represent how many plates ana has left to wash at a particular time after her start at 7: 15. explain your reasoning.

She washed 30 plates from 7:30 to 7:35so she washed 30 plates in 5 minutes30/5 = 6 plates per minute

so if she started washing plates at 7:15 and ended at 7:38...how many plates did she wash
from 7:15 to 7:38 is 23 minutes...and if she can wash 6 plates per minute, then in 23 minutes, she can wash (23 * 6) = 138 plates <==

the equation...
y = -6x + b...with b being the number of plates she started with and x being the number of minutes and y being the plates she has left to wash...I am not 100% sure on this equation...I am so sorry

I'm sure the answer is a
