Answer:
B. Fixed fee for Company B is greater than Company A
Step-by-step explanation:
Company A:
A(n) = $0.99 + $0.25n
The function above is given in slope-intercept form, A(n) = mx + b (rewritten as A(n) = b + mx)
The unit rate (m) = per minute fee = $0.25
Fixed fee (b) = $0.99)
Company B: let's find the fixed fee (b), which is the y-intercept.
The y-intercept is the point on the y-axis where the line intercepts the y-axis.
If we draw a straight line, we would observe that the y-intercept (b) would be between 1.20 and 1.40.
Therefore, fixed fee for Company B would be between $1.2 and $1.4. this is greater than the fixed fee for Company A, which is $0.99.
Therefore, the statement that must be true is:
B. Fixed fee for Company B is greater than Company A
