Please help! Easy math! SUV Costs: y = 2,840x + 17,980
Car Costs: y = 3,210x + 17,980
If we let x = 0 represent the initial cost of each vehicle, which one costs the least initially?
a. SUV
b. Car
c. They are the same.

rounding to the nearest thousandth would be 452,000

your answer is a

step-by-step explanation:

4*4*4*4=256

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.
