x = abc/ (a+b)
Step-by-step explanation:
x/a + x/b = c
Multiply by ab to get rid of the fractions
ab(x/a + x/b) = abc
bx + ax = abc
Factor out an x
x( b+a) = abc
Divide each side by (a+b)
x ( a+b)/ (a+b) = abc/ (a+b)
x = abc/ (a+b)
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
