Acostomer purchases 2 salad bars at $3.49 each. she gave you a coupon worth 50¢ off each salad bar and a $10.00 bill. how much change will you give her (excluding tax)?

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
