Answer:
143
Step-by-step explanation:
Since there are 19 pizzas, and each pizza had 8 slices, we can get the total amount of slices by multiplying 19 and 8, which is 19*8=152(slices)
Now we know that there are 152 slices in total, and Miguel ate 9 slices, then there will be 152-9=143(slices) left for the club
Hope this will help:)
