jamal is comparing his transportation options for an upcoming trip.
he's considering a rental car and a taxi service. based on his planned
routes during his trip, he expects a taxi service would cost about $128. jamal could also get a rental car for a daily rate and unlimited miles.
if jamal's trip will last 4 days and he expects to pay about $24 for gas, which graph shows the range of car rental rates that would be
cheaper than the taxi service?

30

step-by-step explanation:

times by times

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.
