Suppose that it costs ​$20 to place a classified advertisement in the​ newspaper, plus ​$6 for each line. Then the cost to place an ad x lines long is given by y​ dollars, where y = 6x + 20.

Express as an ordered pair the fact that a 16 line ad costs ​$116.

Respuesta :

y = 6x + 116

x = 16 , since x represents the variable of how many lines needed to place the ad

Do not change $6 as it is the price for each line of ad

116 is the requested price for an ad

final answer :
y = 6 ( 16 ) + 116
y = 212
