So in this question, we are given these exchange rates, and they say if one great british pound is worth 25 .7382 mexican pesos in the fourth quarter, how many japanese yen could a trader buy for 1 ,850 of those mexican pesos? give your answer to the nearest toll number.
00:26
So the first thing is i'm going to notice that i'm only interested in the fourth quarter, and i'm really only interested in mexican pesos, great britain pounds, and japanese yen.
00:43
So it's really this number here that's going to end up being important.
00:48
Everything else is going to be irrelevant in this question.
00:53
Okay.
00:53
So the first thing they said is that one great british pound is to 25 .7382 pesos.
01:09
And we're going to set up a proportion to figure out how many great british pounds can i buy for 1850 pesos to begin.
01:18
So one great british pound is to 25 .7382 pesos as x great british pounds are to 1 ,850 pesos.
01:36
And so to solve this equation, i'm just going to multiply both sides by the 1850.
01:42
So we're getting 1 over 25 .782 times 1850.
01:54
Equals x.
01:55
And we'll go to our calculators and we compute 1850 divided by that 25 .7382, giving me 71 .8776...
