Step-by-step explanation:
The fractions are: and
. Let's take a look at the denominators: 5 and 3. The LCD of 5 and 3 is 15. 5x3=15, 3x5=15. So now we would multiply the denominators to make them the same number like this:
and
. Remember that if you multiply the denominator by a certain number, you must multiply the numerator by the same number as well. For example, in
, we multiply 3 by 5 and 2 by 5. Same number. Now with that out of the way, let's work on the equation:
+
. We know it is the same as
and
. So now all we do is add the numerators together: 5+10=15 or
. Now we have to reduce the fraction.
can be reduced to 3 by dividing 15 by 5=3. The final fraction is
or can be simply put as 3 since 3/3 is a whole number. That's it - you're done!
Answer:
a; she will have $8812
b: It will be enough for her trip
Step-by-step explanation:
In this question, we are tasked with calculating how much a certain value in a savings account that is earning an interest that is compounded annually will be worth.
To calculate this, we use the compound interest formula;
A = P(
Where A is the amount after that number of years which of course we want to calculate
P is the principal amount which is the amount we are investing which is $6439 according to the question
r is the interest rate which is 4% = 4/100 = 0.04
t is the time which is 8 years
n is 1 which is the number of times interest will be compounded annually
We plug these values as follows;
A = 6439(1 + 0.04/1)^8
A = 6439(1.04)^8
A = $8,812.22
This amount is greater then the needed $8,500 for the trip and of course it will be enough
