Textbook Pg. 62 #25

25. create a word problem that involves operations with rational numbers in decimal form. Make sure you can solve your problem. Then, have a classmate solve your problem

If 3 pizzas were cut into 8.5 slices per pizza then 2.145 slices were eaten but 0.503 of a slice was left over with 2 extra pizzas that was ordered recently, how many pizza slices are there left?

Answer:  3*8.5-2.145+0.503+8.5*2 = 25.5-2.145+0.503+17
                                                         = 40.858

There would be 40.858 slices of pizza left
