Question

Suppose that it costs $31 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 +31.

Answer 1

Explanation:

Based on the given information, the cost to place an ad x lines long can be calculated using the equation:

y = 6x + 31

Where:

- x represents the number of lines in the advertisement.

- y represents the cost in dollars to place the ad.

The equation y = 6x + 31 represents a linear relationship between the number of lines and the cost of the advertisement. The fixed cost to place the ad is $31, and an additional $6 is added for each line.

For example, if the advertisement is 5 lines long, we can substitute x = 5 into the equation:

y = 6(5) + 31

y = 30 + 31

y = 61

Therefore, the cost to place a 5-line ad would be $61.
