If the foreign exchange rate between the u. s. dollar and the japanese yen is 1: 90, how many yen will you get for $15?

Ratio shows the relative sizes of two or more values.

Given: exchange rate between the U.S, dollar and the Japanese yen is:

1 : 90.

Let x be any number,

then;

Number of U.S. dollar be x

and

Number of Japanese Yen be 90x

Given: U.S. dollar = $ 15

That is;

x = 15

then,

Number of Japanese yen = 90x = yen

Therefore, 1350 yen you will get in exchange for $ 15.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

600,000,000,000, or 6e14
