1.2: entrance fees a state park charges an entrance fee based on the number of people in a vehicle. a car containing 2 people is charged $14, a car containing 4 people is charged $20, and a van containing 8 people is charged $32. how much do you think a bus containing 30 people would be charged? if a bus is charged $122, how many people do you think it contains? what rule do you think the state park uses to decide the entrance fee for a vehicle?

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

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.
