Solve for c by simplifying both sides of the equation, then isolating the variable.
C=36.5

Answer:

Step-by-step explanation:
Cost of 4 TVs = $ 680
<u>Finding</u><u> </u><u>the</u><u> </u><u>cost</u><u> </u><u>of</u><u> </u><u>1</u><u> </u><u>TV</u>

<u>Finding</u><u> </u><u>the </u><u>cost</u><u> </u><u>of</u><u> </u><u>7</u><u> </u><u>TVs</u>
Since, the cost of 7 TVs is more than that of 1 TV. So, the cost of 1 TV is multiplied by 7

Hope I helped!

It would take 5.2 hours to travel the distance
Answer:
y= 8000x + 2000
Step-by-step explanation:
to find the formula we can use the points given in the question:
the slope:
to get the slope we can take the 2 points, (0,2000) and (2,18000) where x values are time and y values are bacteria
now using slope-intercept form we can get
which gives a slope of 8000 meaning for each hour there are 8000 new bacteria
intercept:
since we start with 2000 bacteria we know this is the y intercept so when x is 0
formula:
y=8000x + 2000
