A food truck vendor averages 150 tacos sold when the price per taco is $4 . A study shows that the average number of tacos sold will increase by 25 tacos for every $1 that the price per taco is lowered.

Which equation models the food truck's average sales in dollars, s, in terms of the price per taco, x?

s = 25x + 250
s = -25x + 250
s = 25x^2 + 250
s = -25x^2 + 250

Given that a food truck vendor averages 150 tacos sold when the price per taco is $4, and a study shows that the average number of tacos sold will increase by 25 tacos for every $1 that the price per taco is lowered, to determine which equation models the food truck's average sales in dollars, s, in terms of the price per taco, x, the following calculation must be made:

  • S + 25 = X - 1
  • 150 + 25 = 4 - 1
  • 150 + 25 x 2 = 4 - 1 x 2

Therefore, the equation that models the food truck's average sales in dollars, s, in terms of the price per taco, x is S + 25 = X - 1.
