What is the solution to the problem expressed to the correct number of significant figures? (102,900 ÷ 12) (170 × 1. 27) = ? A. 8,790 B. 8,790. 9 C. 8,791 D. 8,800.

I'm pretty sure this is the answer

Step-by-step explanation: k is increased by 20% which means new k will be 1.2k. Similarly new x will be 1.2x and

new y will be 1.2y.

So, new T will be 1.2x×1.2x

1.2y which is equal to 1.2kx/y. Therefore, now we have

original T =kx/y

and new T =12.kx/y

increase in T is given by 1.2kx/y −kx/y which is equal to 0.2kx/y.

original     increase

kx/y         0.2kx/y

100 ?

?= 0.2kx/y ×100/kx/y

which is equal to 20% (cancel kx/y)
