B. 10,450

We can see that 4 is underlined and next digit to 4 is 5, which is equal to 5, so we will round up our answer to nearest hundred place.

C. 126,234

We can see that 6 is underlined and next digit to 6 is 2, which is less than 5, so we will round down our answer to nearest thousands place.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

he earned 78.75 in interest.
