Dolores and four friends went to buffet dinner. the total cost was at most $130 including the $20 tip they left. how much did each pay for the buffet? write an inequality

Buffet = total - tip = $110

There were total 5. Consider, x is the amount paid by each.

Then, inequality would be 5x = 110

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)

yes
