Question

Consider the problem of washing dishes by hand. suppose washing a dish takes 30 seconds and drying a dish takes an additional 30 seconds, and we want to find out the time to wash 11 dish. if the the size of a problem is represented by n. what is the value of n in the given problem?

Answer 1

I think you would do 30+30(11)=n

30+30=60

60x11=660

n=660

Sorry if this isn't right I did what my teacher taught me.
