Aman paid $71.40 for a radio. the radio was marked 15% off the original selling price. what was the original selling price?

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

- (2, -7)

- lines r and s and lines t and u must be parallel

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

hd extra 3-7 x d en is the answer
