The lopez family had dinner at their favorite restaurant. a 6% sales tax was added to their bill. amy paid the bill with a $15 gift certificate plus $52.90. how much did the family's dinner cost before tax? round your answer to the nearest penny.

hint: use the equation p + rp = t,
where p is the price before tax, r is the sales tax rate, and t is the total price, including tax.

$ 63.83

$ 62.83

$ 64.06

$ 70.97

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

no

step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

the answer is c hope this
