Based on the context provided in your table for lawns mowed (x) and money earned (y), let's fill in the blanks with appropriate responses:
A. Every lawn mowed is 42 dollars earned. (This is determined by calculating the unit rate: $294 / 7 lawns = $42 per lawn.)
B. Dollars/1 lawn is called a Unit rate. (This is the definition of unit rate, describing the amount of money earned per individual lawn mowed.)
C. This relationship is proportional because 0 lawns mowed is 0 dollars earned. (A proportional relationship indicates that as one quantity increases, the other increases by a constant rate, and if you have zero lawns mowed, you earn zero dollars.)
So the finalized responses are:
A. 42
B. Unit rate
C. proportional (and 0 for the second part in C, not explicitly needed in the list but related to the concept of proportional relationships).
