Answer:
7 software packages
Step-by-step explanation:
Given,
Signing amount = $ 225,
Additional amount for each software package = $ 25
Thus, the total amount for x software packages = signing amount + additional amount for x packages
= 225 + 25x
If total amount ≥ $ 400
225 + 25x ≥ 400
25x ≥ 400 - 225
25x ≥ 175

Hence, the minimum number of software packages that she must sell would be 7.
Answer:
Relationship between distance and time in simplified form as a unit rate is; 
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1, such as 5 feet per second or 3 miles per hour, they are called unit rates.
Unit rate = 
From the given table:
Take any
time = 4 hours and distance= 188 miles
then, by definition of unit rate;
Unit rate = 
Since, this is the constant rate.
Therefore, the relationship between distance and time in simplified form as a unit rate is;
