Ted builds three types of guitars: archtops, electrics, and acoustics. Suppose that it takes Ted x hours to build an archtop guitar, y hours to build an
electric guitar, and z hours to build an acoustic guitar.
If Ted charges $90 per hour for an archtop guitar, $45 per hour for an electric guitar, and $65 per hour for an acoustic guitar, write an equation
relating x, y, and z if Ted builds $9240 worth of guitars.

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.
