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 was
hing 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 7:35.....so she washed 30 plates in 5 minutes.....30/5 = 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
Diana's age=21 years Carmen's age=x years Andrew's age=2x years 21+x+2x=45 21+3x=45 3x=45-21 3x=24 x=24/3 x=8 2x8=16 Carmen is 8 years old and Andrew is 16 years old. Hoped that helps:)
