A television costs the same as 5 microwaves.
00:04
3 microwaves cost the same as 8 blenders.
00:06
12 blenders cost the same as 7 rice cookers.
00:09
And 2 rice cookers cost $375.
00:12
How much do 3 televisions cost? let's go through each of our statements here and write a mathematical equation.
00:22
Our first statement is that 1 television costs the same as 3 microwaves.
00:27
So let's label television, the price of television, as tv.
00:32
So tv will correspond to the price of a television.
00:40
And let's say that mw will correspond to the price of a microwave.
00:51
So our first line here tells us that 1 tv is equivalent to 3 microwaves.
01:11
Our next problem statement is that 3 microwaves cost the same as 8 blenders.
01:18
So let's label the price of a blender with b.
01:31
So this second statement translates mathematically as 3 mw, 3 microwaves, is equivalent to the price of 8 b, 8 blenders.
01:45
Our next statement is that 12 blenders cost the same as 7 rice cookers.
01:48
So let's label the price of a rice cooker with rc.
02:01
So we now have that 12 b, 12 blenders, is equivalent in price to 7 rc, 7 rice cookers.
02:18
And finally, our last statement is that 2 rice cookers cost $375...
