A foreign country uses the stellar as its currency. Before a trip to that​ country, Jon wants to exchange ​$1,300 to stellar. Which of Bank A and Bank B has the better exchange​ rate? How many more stellar would he get if he exchanged his ​$1,300 at the better exchange rate instead of at the other​ rate?

Answer:

✔️Bank A has a better exchange rate

✔️Mr Jon would get 6,630 Stellar if he uses the bank with the better exchange rate

Step-by-step explanation:

✔️The bank that has the greater unit rate or constant of proportionality is the bank that has a better exchange rate.

Exchange rate of bank A:

Exchange rate = unit rate or constant of proportionality = y/x

Where, x = dollars, and y = stellar

Exchange rate/constant of proportionality, using one pair, (80, 408) would be:

y/x = 408/80 = 5.1 (this means 5.1 Stellar per dollar)

Exchange rate for bank A:

Using a point on the proportional graph, (10, 50),

Exchange rate/constant of proportionality = y/x = 50/10 = 5 (this means 5 Stellar per dollar)

Therefore, we can conclude that Bank A has a better exchange rate, because it has a greater constant of proportionality. This would mean more Stellar for Jon per dollar he wants to exchange.

✔️If Jon exchanged $1,300 at the better rate that Bank A offers, he would get the following amount of Stellar:

1,300 × 5.1 = 6,630 Stellars

Bank A has a better exchange rate than Bank B. The exchange value as per bank A is 130 stellars more than that of Bank B.

What is the exchange rate?

An exchange rate is a rate at which one currency will be exchanged for another currency.

The relation between Dollars and Stellars as per Bank A will be a straight line

Equation of this straight line

[tex]y = \frac{510-408}{100-80} * x +c\\\\y = 5.1x + c[/tex]

For the value of c put y = 510 and x= 100 in above equation

c = 0

y = 5.1x

y = stellars

x = dolars

Exchange for $1300 as per bank A

y = 5.1*1300 = 6630

Similarly, the relation between Dollars and Stellars as per Bank B will also be a straight line

Equation of this straight line will be

[tex]y =mx\\\\y = \frac{250-0}{50-0} * x\\\\y = 5x[/tex]

Exchange for $1300 as per bank B

y = 5*1300 = 6500

Therefore, bank A has a better exchange rate than bank B. exchange value as per bank A is 130 stellars more than that of bank B.
