Answer:
Definition: Exponents, or powers, are a way of indicating that a quantity is to be multiplied by itself some number of times.
Example: 




Let "per month" = m
The inequality is
1.5m + 4 ≥ 7
+ 4: Her hair right now is 4 cm long
1.5m: Her hair grows 1.5 per month (m)
≥ 7: She wants it to be at least 7 or more.
1.5m + 4 ≥ 7 is your answer
