A meal costs 50.30. which is the best estimate of the final costs with 4% sales tax and 15% tip

$59.84

Step-by-step explanation:

Original meal: $59.30 + $7.525 (tip) + $2.014 (sales tax) = approximately $59.839/$58.84

b

step-by-step explanation:

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)
