A computer cost £900. It is on sale for 25% off. You also need to pay 6% sales tax. What is the final price of the computer?
Vesna [10]

First we have to find 25% of 900 pounds (i hope that's the right currency). so 900 x .25 = 225

so we subtract 225 from 900 and get 675 pounds.

to find sales tax we have to find 6% of 675, so 675 x .06 = 40.50

675 + 40.50 = 715.5 pounds

Sales rise from £400 a week to £504 a week. Calculate the percentage increase
Andrew [12]

Answer:

26%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

Here, the new number is £504, and the old number is £400.

percent change = (£504 - £400)/(£400) * 100% =

= £104/£400 * 100% = 0.26 * 100% = 26%

How do I solve 34-5x+2(x-2)=15
LenKa [72]
34-5x+2(x-2)=15      1st get rid of () by distributing the 2.
34-5x+2x-4=15         Now collect like terms.
30-3x=15                  Get -3x by itself by subtracting 30 in both sides.
-3x=-15                     You want X by itself so divide by -3 on both sides.
x=5
