Martha is considering acquiring another piano for her piano academy. The cost of a new Steinway grand is around $148,000. Pianos depreciate at a rate of about 5% per year, and the academy’s investment fund typically earns a return of about 10% per year. Additional revenues obtained through the increased teaching capacity enabled by the piano and renting the piano out for performances are expected to be about $30,000 per year. Calculate the maximum price the piano academy is willing to pay for the piano.

b is the answer that makes most sense

step-by-step explanation:

good job you smart son of a gun you are smarter that einstein. 7

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.
