Answer:
The answer is 7.
Step-by-step explanation:
You solve this by using PEMDAS. You solve the multiplication and division before addition and subtraction leaving you with 6 + 5 - 4. You then do addition/subtraction from left to right giving you 11-4. Ultimately your final answer will be 7.
Follow PEMDAS - but backwards.
(Parenthesis, Exponents. Multiplication, Division, Addition, Subtraction)
First SUBTRACT 5 from each side of the equation...
3x/5 + 5 (- 5) = 20 (- 5)
3x/5 = 15
Next MULTIPLY each side by 5...
3x/5 ( • 5) = 15 (• 5)
3x = 75
The third step if you need is to DIVIDE ...
3x ( / 3) = 75 (/ 3)
x = 25
Answer:
$3781.19
Step-by-step explanation:
Let us assume that the student has to earn $(1900 + x) by September 1 so that he can pay the $1900 tuition fee by September 1 and the remaining $x will grow at 3% simple interest to make him able to pay another tuition fee of $1900 by January 1.
So, we can write 
{Because September 1 to January 1 is 4 months and the monthly simple interest rate is 
%}
⇒ 1.01x = 1900
⇒ x = $1881.19 (Rounded to the nearest cents)
Therefore, the student has to earn $(1900 + 1881.19) = $3781.19 (Answer)
