Natsumi paints walls for a living. she paints at a constant speed, and then she takes a constant amount of time to clean up.
the table compares the total area natsumi paints (in square meters) and the time it takes natsumi to finish painting and cleaning up (in hours).

(table attached below)

how long does it take natsumi to paint 1 square meter?

hours

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
