A cell phone plan costs $200 to start. Then there is a $50 charge each month. a. Graph the cost of the cell phone plan over a period of two years, using months as the units of time (on your own paper). Is there a proportional relationship between time and the cost of the cell phone plan? Explain how you know.
b. Suppose you drew a line parallel to the line you graphed that goes through the point (0,350) and this line represented the pricing plan for another company. What is the startup fee and monthly cost for this plan?

u dumb boi

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

i believe the answer is 323 ft
