Answer:
it cost $39.95 in a month when you use the internet for 14 hours
Step-by-step explanation:
internet company charges $4.95 per month plus $2.50 for each hour
Let x be the amount of hours internet used
for 1 hour, charge is 2.50
for x hours , charge is 2.50x
To get linear equation we use y=mx+b
m is the slope and b is the fixed cost
fixed cost b= 4.95 and slope m = 2.50
So equation becomes y = 2.50x + 4.95
we need to find the cost y for 14 hours
So we plug in 14 for x and find out y
y = 2.50(14) + 4.95= 39.95
