Olivia + Holly = $19.99
We are given that Olivia had $11.52, so plug in 11.52 for Olivia in the equation.
11.52 + Holly = 19.99
Subtract 11.52 from both sides.
Holly = 8.47
Holly put $8.47 toward the DVD.

No. The area of a square/rectangle is length * height, and 4 * 20 is 80m^2. Because Yoshi has a can of paint that can cover 81m^2, and 81m^2 > 80m^2, Yoshi does NOT need to buy more paint.
Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):
265 + 48h = 553
Substract both sides by 265:
48h = 288
h = 6
