25% off of $1400 equal: 1400 + .25 = 350, so 1400 - 350 = 1050
So now the computer with 25 % off is $1050.
tax 7%, means 1050 + .07 = $73.50 (sales tax charge)
Total computer with 25% off plus 7% tax equal:
$1050 + 73.50 = $1,123.50
Amir has saved $1200, so he has enough money to purchase the computer.
3(x-4)>= 5x+2
Distributing 3 on x-4
3(x)-3(4)>=5x+2
3x-12>=5x+2
Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides
-2x >=14
Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is
x<=-7
