How much will she pay in all, purchase plus tax

1. $137.75

3. $149.15

Step-by-step explanation:

1.

12.25+125.50=137.75

3. 8.25% of 137.75= 11.4

137.75+11.4=149.15

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
