Tricky but not crazy hard. You could use th x/y method where you turn it into a cross multiplication fiasco.
or you can try your guesses through what ever equals 1/2 when you add one to the denominator. the answer you are looking for is 2/3
2/3 + 1 for the numerator = 1.
2/3 + 1 for the denominator = 1/2.
Answer:
$5 bill
Step-by-step explanation:
If Rhonda has $13 and she has a $5 bill and 3 $1 bills, then she has
5 + 3(1) + x = 13
5 + 3 + x = 13
8 + x = 13
x = 5.
The last bill must be a $5 bill to equal the remaining $5.
350000 = 270000(1.05)^n
1.05)^n = 350000/270000 = 1.296296
n = log 1.296296 / log 1.05 = 5.3 years answer
