#### Answer

You must sell 3 or more gardens to meet your goal.

#### Work Step by Step

If you want to sell at least 10 gardens, then your total number sold must be greater than or equal to 10.
The total number of gardens you will sell is the sum of your remaining sales and the number sold on Monday and Tuesday. Let s represent your remaining sales:s+3+4≥10. Solve for s:
s+3+4≥10⟶ combine like terms
s+7≥10⟶ subtract 7 from each side-
s≥3
You will need to sell at least 3 more gardens to reach your goal of selling at least 10.
