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
