Ineed the answer to be right and explain how to do ! the restaurant charges $1.75 for the first breakfast taco and $1.25 for each additional taco. if y represents the total cost and x represents the total number of tacos purchased, what is the function rule that describes this pattern? a. y= 1.75 - 1.25(x-1) b. y= 1.75 - 1.25(x+1) c. y= 1.75 + 1.25(x+1) d. y= 1.75 + 1.25(x-1)

y= 1.75 is the starting contest the additional amount of tacos is X so x*1.25 will give the price of more tacos.

y=1.75+1.25(x+1) is the answer

Step-by-step explanation:

Hi!

The correct answer is:

D. y= 1.75 + 1.25(x-1)

Step-by-step explanation:

If the charge for first breakfast taco is $1.75. So this is a constant of this function.

y= 1.75 + 1.25(x-1)

Moreover, for each additional taco, we have to charge $1.25 plus.  If the first taco is not an additional taco, then we don't have to count the first taco and it will be represent like:

y= 1.75 + 1.25(x-1)

Then if we replace some values of x on the function we have:

y(1)= 1.75 + 1.25(1-1) =  1.75 + 1.25(0) = 1.75 for the first taco.

y(2)= 1.75 + 1.25(2-1) =  1.75 + 1.25(1) = 3 for the first and the second taco.

and so on..

a - base

b - exponent

so,
