8 25/1000 = 8.025 <===
The whole number stays to the left of the decimal...and since the 25 is over 1000, the last digit has to be in the thousandths place.
Let assume x be the sale price
A clothing store advertises that it is having a 25% off sale.
The sale price with 25% discount is f(x) = sale price - 25% of sale price
f(x)= x - 0.25x = 0.75x
For one day only, the store advertises and additional savings of 10%.
The sale price with 10% discount is g(x) = sale price - 10% of sale price
g(x)= x - 0.10x = 0.90x
Use composition function
g(f(x)) = g( 0.75x) = 0.90(0.75x) = 0.675x
That is 0.675/100 = 67.5%
The total percent discount = 100% - 67.5% = 32.5%
what would be the sale price of a $40 sweater?
Here sale price x= 40
So we plug in 40 for x
g(f(40)) = g( 0.75(40)) = 0.90(0.75(40)) = 0.675(40) = 27
The sale price of sweater = $27
Hi Brainiac
2/5 + p = 4/5 + 3/5 p
Simplify
p + 2/5 = 3/5 p + 4/5
Subtract 3/5p from both sides
p + 2/5 -3/5p = 3/5p + 4/5 -3/5 p
2/5 p + 2/5 =4/5
Subtract 2/5 from both sides
2/5 p +2/5 -2/5 = 4/5 -2/5
2/5 p = 2/5
Divide both sides by 2/5
2/5 p / 2/5 = 2/5 /2/5
p = 1
I hope that's help:)
X-7 - -2x-5
answer is 2/3
X-7 + 2X= -2x-5+2x
3x-7= -5
3x-7+7= -5+7 (getting x alone)
3x=2
divide by 3 to get x
3x/3 =2/3
x=2/3
