Plan A = 50 + 0.05(x-500)
Plan b = 20 + 0.06 (x-200)
set A equal to B
50 + 0.05 (x-500) = 20 + 0.06(x-200)
50 + 0.05x - 25 = 20 + 0.06x -12
rearrange like terms on one side.
50 - 25 -20 +12 =0.06x -0.05x
17 = 0.01x
x = 1700 minutes.
all you have to do is add 64 + 45 which equals 109 then subtract from fifty which is b 47
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.
