FAYE BOUGHT 3 PIZZAS FOR LUNCH. EACH PIZZA HAS 10 SLICES IN IT. IF 90% OF THE LUNCH WAS EATEN, HOW MANY SLICES WERE LEFT
3 * 10 = 30 slices
30 * 0.9 = 27 slices were eaten
How many slices were left?
This is wrong

To find out how many slices were left, we first need to calculate how many slices were eaten.
Since Faye bought 3 pizzas and each pizza has 10 slices, the total number of slices initially is 3 * 10 = 30 slices.
To calculate how many slices were eaten, we need to find 90% of the total number of slices:
90% of 30 slices = 0.9 * 30 = 27 slices.
So, Faye ate 27 slices.
To determine how many slices were left, we subtract the number of slices eaten from the total number of slices:
Total number of slices - Slices eaten = Slices left
30 slices - 27 slices = 3 slices.
Therefore, there were 3 slices left after 90% of the lunch was eaten.
