Multiply 99 by 20%.
Convert 20% to a decimal ⇒ 0.2

99 × 0.2 = 19.8

Subtract 19.8 from 99.
99 - 19.8 = 79.2

Now multiply 79.2 by 7%.
7% ⇒ 0.07
79.2 × 0.07 = 5.544

Add 5.544 to 79.2.
5.544 + 79.2 = 84.744

Round to the hundredths place because it's money :)
84.744 ⇒ 84.74

Karina spent $84.74 to buy the camera.
