All computers are on sale for 10% off the original price. If x is the original price of the computer, then the function that represents the price after only a 10% discount is:

Asap
P(x) = x - 0.1x

P(x) = 0.9x

The function that gives the price, C, if only a $150 coupon is used is:

C(x) = x - 150

Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.

C(P(x)) = 0.9x – 150

P(C(x)) = 0.9x – 150

C(P(x)) = 1.9x – 150

P(C(x)) = 1.9x – 150

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
