To simplify that question, you would normally say "20 is 80 percent of what number"
To find the answer you must grab the number 20 and divide it by 80% or 0.8
20 ÷ 80% = 25
20 ÷ 0.8 = 25

There are 52 weeks in a year, so 52x represents how much she earns in a year.

B. 0.18
Step-by-step explanation:

0.25·0.70 = 0.175 ≈ 0.18 . . . . matches choice B
The slope-intercept form: y = mx + b
(m - slope, b - y-intercept)
We have y = -2. It's the slope intercept form where m = 0 and b = -2.
y = -2 → y = 0x - 2
