Question

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 1

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
