Since Amanda originally paid $35 and the sales tax is 7%, we have to multiply 35*.07 which equals 2.45. You now have to add the factor to $35 and you get $37.45.
The price of the stereo is $37.45.
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
If you use the elimination method, add both equations together to eliminate a variable. You will get 5x=15. x=3. Replace x in the equations with 3 to get y =7, so your answer is A, (3,7.) I hope his helped!. Please give brainliest!
258/300 simplified will be 43/50
As a decimal, it would be 0.86
As a percent, it would be 86%
