Eli needs to save $235. to earn money, he plans to mow lawns and charge $21 for each, write two estimates eli could use to determine the number of lawns he needs to mow. decide which estimate you think is the better one for eli to use

To determine the number of lawns he needs to mow to earn the desired money, Eli could perform a simple addition problem, adding $21 per lawn until he reached his goal number. This equation would be: 21 + 21 = 42 + 21 = 63 + 21 = 84 + 21 = 105 + 21 = 126 + 21 = 147 + 21 = 168 + 21 = 189 + 21 = 210 + 21 = 231 + 21 = 252. However, a better way would be to divide the desired amount by the cost per lawn and round to the nearest whole number. That equation is 235 / 21 = 12 lawns.
