In bowling, scoring is done by frame, with a frame consisting of two attempts (ball rolls) to knock
down all the pins. A spare occurs when it takes both attempts to knock down all 10 pins. The score for a
spare in the current frame is found by adding the number of pins knocked down in the first attempt of the
next frame to 10, the number of pins knocked down in the spare in the current frame.
a.
Write an expression for the score of the spare if you knock down p pins in the first attempt of the
next frame.
b. What is your score for a spare if you knock down 7 pins in the first attempt of the next frame?
