To round to the nearest thousand, we check the digit in the hundreds place. If it is less than 5, we round down, else we round up to the next thousand.
In this case, the digit in the hundreds place is "6" and "6" is 5 or more, so we round up to the next thousand.
15 680 ≈ 16 000
X is the unknown value. The word "of" means to multiply. 40% in decimal form is 0.40. So "40% of a value" means "0.40x".
20=0.40x
Divide both sides by 0.40:
x=50
