Answer:
The inequality 7.50c - 350 ≥ 700 can be used.
Step-by-step explanation:
Given that:
Amount spent on materials = $350
Amount the council needs to earn = $700
Selling price per corsage = $7.50
Number of corsages sold = c

Hence,
The inequality 7.50c - 350 ≥ 700 can be used.
Answer:
Step-by-step explanation:
The given function is
The range refers to the values of y for which x is defined.
We solve for x to obtain;
This is a polynomial function in y.
x is defined for all values of y.
Therefore the range is all real numbers.
or
The first choice is correct.
