The Kellys are having dinner at a local restaurant. Mr. Kelly wants to give the server a 15% gratuity, and the sales tax is 6.5%. He will use the amount of the bill to find each additional amount. Question 1
Part A

Which components would Mr. Kelly use to write an equation to determine the total cost of the meal, given the amount of the bill, x?

Select all the components of the equation.

A. x

B. x+0.15

C. 0.15x

D. x+0.65

E. 0.65x

F. 0.065x

Question 2
Part B

By what percent does the cost of the meal increase with tax and gratuity?

Enter the correct answer in the box.

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

Ithink it would be 1.24 pounds
