209 to the nearest hundredth is 200.
209 to the nearest tenth is 210.
To find this, turn the word question into an equation.
"One less than" means - 1, which is 1 being subtracted from something.
"half a number" means 1/2x, since 1/2 is half and x is unknown.
"is 12" means = 12, which is something equals 12.
Putting this in order would be 1/2x, then - 1, then = 12.
As an equation, this is 1/2x - 1 = 12.
So the equation is 1/2x - 1 = 12
Now you must find the number by solving this equation.
1/2x - 1 = 12
First, add 1 to both sides.
12 + 1 = 13
1/2x = 13
Now multiply both sides by 2.
This way, x will be isolated since 1/2x • 2 = 1x, and 1x = x.
13 • 2 = 26
x = 26
The number is 26.

Answer:
$1.65
Step-by-step explanation:
If h is the price of a hot dog, then the total bill was ...
4(2h +1.25) = 18.20
2h +1.25 = 4.55 . . . . . . divide by 4
2h = 3.30 . . . . . . . . . . . subtract 1.25
h = 1.65 . . . . . . . . . . . . . divide by 2
The price of one hot dog was $1.65.
