Answer
Find out the how much money was in the account after
years.
To prove
Formula

As given
Tracy deposited $59 into a bank account that earned 3.5% simple interest each year.
Principle = $59
Rate = 3.5 %

i.e

Time = 1.5 years
Put all the values in the equation

= \frac{309.75}{100}[/tex]
= $3.1(approx)
Amount in the account = Principle + Simple interest
= $59 + $ 3.1
= $ 62.1
1 Dollar = 100 cent
Now convert $62.1 into cent.
= 62.1 × 100
= 6210 cent
Therefore the money in the account is 6210 cent .

Answer:
2x + y = 18
y = 4x - 12
x = 5, y = 8
Step-by-step explanation:
x = 1st number
y = 2nd number
We can use the substitution method as we know what 'y' equals; that value will get plugged in for 'y' in the first equation as follows:
2x + 4x - 12 = 18
6x - 12 = 18
6x = 30
x = 5
y = 4(5) - 12 which is 20-12 or 8
y = 8
