Answer:
291.25 talk minutes would produce the same cost for both plans.
Step-by-step explanation:
Both plans can be modeled by a first order equation in the following format:
In which is the initial cost, f is the fee that is paid for each minute, and t is the number of minutes.
Cost of the first plan:
The problem states that the first plan charges a rate of 24 cents per minute, which means that .There is no initial cost, so .
The equation for this plan is:
Cost of the second plan:
The problem states that the second plan charges a monthly fee of $34.95 plus 12 cents per minute. So and
The equation for this plan is:
Find the number of talk minutes that would produce the same cost for both plan:
This is the instant t in which:
291.25 talk minutes would produce the same cost for both plans.
Answer:
b
Step-by-step explanation:
Please mark brainliest
slope intercept form is y = mx+ b
lets get the equation in that form
8y = 2x+4
divide each side by 8
8y/8 = 2x/8 + 4/8
y = 1/4x + 1/2
the slope or m is 1/4
Choice C
Answer:
Step-by-step explanation:
Your answer is 9.
53 x 2 = 106
106 + 20 = 126
126 / 14 = 9 !
