10²(3.815×10²)

3.815×10⁴ (option 4)

4×10³×5×10⁷

4×5×10³×10⁷

(4×5)(10^(3+7)

guajiro [1.7K]

Answer: $47.06 if you do not round or $47.07 if you are required to round up.


Step-by-step explanation:

$43.99× .07 = 3.0793

$43.99+ $3.07 = $47.06

(If you round up then follow below)


$43.99× .07= 3.0793 (the 9 would cause you to round the 7 up to 8)

$43.99+ $3.08= $47.07

19035 × (1 - 10%) = 19035 × (1 - 0.1) = 17131.5
