Greg earns 2% commission on each car he
sells, plus a base salary of $500 per week. If
his total car sales in one week was $68,775,
find his take-home pay for the week.

$1875.50

Step-by-step explanation:

s = salary; c = car sales

s = 500 + (c × 0.02)

= 500 + (68775 × 0.02)

= 500 + 1375.5

= 1875.5

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)

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
