Answer:
Trace will need to spend $26.25 for the additional plants.
Step-by-step explanation:
How much she spent for each plant?
Tracy brought 5 trays of plants for $105. Each tray contained 12 plants.
This means that.
12*5 = 60 plants cost $105.
1 plant costs 105/60 = $1.75
How many more money will Tracy need to spend for 15 additional plants?
Each plant costs $1.75.
1.75*15 = $26.25
