00:00:02.920 --> 00:00:05.600
Eggs are sold in boxes and crates.
00:00:06.160 --> 00:00:08.080
Each box contains 12 eggs.
00:00:08.720 --> 00:00:10.920
Each crate contains 42 eggs.
00:00:11.920 --> 00:00:15.560
Josh buys π boxes and π crates of eggs.
00:00:16.440 --> 00:00:23.200
Write an expression for the total number of eggs that Josh buys, in terms of π and π.
00:00:25.440 --> 00:00:33.400
So if we actually want to find the total number of eggs that Josh buys and write an expression for it, then first, weβll start with the boxes.
00:00:34.360 --> 00:00:37.080
So we know that each box of eggs contains 12 eggs.
00:00:37.920 --> 00:00:49.400
So therefore, the number of eggs that Josh gets in boxes is gonna be found by multiplying 12, the number of eggs in a box, by π, the number of boxes that he buys.
00:00:51.520 --> 00:00:57.840
And the way that we actually write that is 12π because weβre actually writing it using algebraic notation.
00:00:58.400 --> 00:01:00.240
We donβt need to include the multiply sign.
00:01:03.160 --> 00:01:18.880
Next, if we actually want the number of eggs that Josh gets from crates, then weβll work this out by multiplying 42, because thatβs the number of eggs per crate, by π, because thatβs the number of crates that he buys.
00:01:21.360 --> 00:01:24.840
And again, we donβt need to write 42 multiplied by π.
00:01:25.520 --> 00:01:28.320
We can actually leave the multiply sign out and just right 42π.
00:01:29.400 --> 00:01:39.840
So therefore, we can say that an expression for the total number of eggs that Josh buys in terms of π and π is 12π plus 42π.
