Practice time P seconds Timing in the Race : R = 58.4 seconds Improvement Record I = 2.6 seconds <u>Race timing = Practice timing - Improvement record</u> <u>R = P - I</u> <u>58.4 seconds = P - 2.6 seconds</u>
Take 2.6 seconds to the left hand side, 58.4 sec + 2.6 sec = P P = 61.0 seconds
Now, subtract improvement record time from Practice time, you get the race time.
<span><span>Suppose you have a choice of 5 pizza toppings and 2 kinds of crust. To find all possible choices, multiply the number of possible toppings (5) by the number of crust choices (2); <span>5 x 2 = 10.</span> If you want to list all the possible choices, you can make an organized list or draw a tree diagram.</span></span>
