7a) Binh brought \( \$ 23 \) with her to the county fair. She purchased a \( \$ 5 \mathrm{~T} \)-shirt and now wants to buy some loc grown plants for \( \$ 2.50 \) each. What are the numbers of plants that she can purchase with her remaining mone

To determine how many plants Binh can purchase with her remaining money, let's break down the problem step by step. ### **Step 1: Calculate the Remaining Money** Binh initially has: \[ \$23 \] She spends: \[ \$5 \quad \text{on a T-shirt} \] So, the remaining money is: \[ \$23 - \$5 = \$18 \] ### **Step 2: Determine the Cost per Plant** Each locally grown plant costs: \[ \$2.50 \] ### **Step 3: Calculate the Number of Plants She Can Buy** To find out how many plants Binh can purchase with her remaining \$18, divide the remaining amount by the cost per plant: \[ \frac{\$18}{\$2.50} = 7.2 \] Since Binh can't purchase a fraction of a plant, we take the whole number part of the result. \[ \text{Number of plants} = 7 \] ### **Conclusion** Binh can purchase **7 plants** with her remaining money of \$18.
