let's assume is simple interest.
Answer:
30- 3x 14
Step-by-step explanation:
Let say that Y is the number of toys you have now and X is the number of the customer. Every customer (X) buy 3 toys, and you have 30 toys at the start. So you can put this equation
30- 3x = Y
Now you have at least 14 toys, in other words, it is more than or equal to 14 (14). The equation will be:
30- 3x 14
