Final answer:
Using a proportional relationship, Renaldo can exchange 49 euros for 77 dollars at the same rate of 7 euros for 11 dollars.
Step-by-step explanation:
The student asked: At the given rate, how many dollars can Renaldo get with 49 euros? To solve this, we need to find the rate of exchange between euros and dollars, and then apply this rate to find out how much he would get for 49 euros. Renaldo exchanged 7 euros for 11 dollars initially. We can set up a proportion to solve for the unknown quantity of dollars for 49 euros:
7 euros / 11 dollars = 49 euros / x dollars
Cross multiply to solve for x:
7x = 49 * 11
x = (49 * 11) / 7
x = 7 * 11
x = 77
So, Renaldo can get 77 dollars for 49 euros at the same exchange rate.
