While vacationing,john has dinner at a restaurant in Japan and his tab

1 yen = 1.25 cents.

100 yens = 125 cents = 1.25$
So 3428 yens = 3428/1.25 $

Is this the final answer? Or do i need to divide 3428 by 1.25$ to get the final answer?

$3428/1.25 is the same as

$3428÷1.25
Yes, you will have to take the calculator and do the division to get the final answer.
Feel free to post the final answer for verification if you wish.

I came up with $ 2,742.4

I apologize that I was completely off.

Let's start over.

1 yen equals 1.25 cents = $0.0125

so by direct proportion:

1 yen : $0.0125
3428 yens : $X

so by cross multiplication:
$X = $0.0125*3428yens/1 yen
= $42.85

To find the cost of the meal in US dollars, we can use the given exchange rate.

First, we need to convert the amount in yen to US dollars. To do this, we multiply the cost in yen by the exchange rate.

Cost in US dollars = Cost in yen * Exchange rate

In this case, the cost in yen is 3,428 yen and the exchange rate is 1 yen = 1.25 cents.

Let's calculate it:

Cost in US dollars = 3,428 yen * 1.25 cents/yen

To get the cost in US dollars, we need to convert cents to dollars. There are 100 cents in a dollar. So, we divide the amount in cents by 100 to get the amount in dollars.

Cost in US dollars = (3,428 yen * 1.25 cents/yen) / 100 cents/dollar

Now, let's simplify the equation:

Cost in US dollars = (3,428 * 1.25) / 100 dollars

Calculating the expression: 3,428 * 1.25 = 4,285

Cost in US dollars = 4,285 / 100 dollars

Simplifying further: 4,285 / 100 = 42.85

Therefore, the cost of the meal in US dollars is $42.85.
