A movie on-demand service charges an 18$ monthly fee. it also charges a 3$ fee per movie rental. if nathan rents 20 movies in a year, how much would the service cost

U.S. adults say the on-demand price range that they'd be willing to pay for a movie currently in theaters is $5 to $8, with the optimum price being $6, a new Hollywood Reporter/Morning Consult poll finds. The survey was conducted among a nationally representative sample of 2,200 adults from March 19 to 21

1. minimum

2. 6400

3. eight

hope this !

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.
