Answer:
The total saving of Alex (a) and Benjamin (b) was 2000$.
=> a + b = 2000 (1)
Alex donates 1/4 of saving, Benjamin donates 1/5 of saving.
Total donation: 440$
=> (1/4)a + (1/5)b = 440 (2)
From (1) and (2):
=>(1/4)(2000 - b) +(1/5)b = 440
=> 500 - (1/4)b + (1/5)b = 440
=> (1/20)b = 60
=> b = 20 x 60 = 1200$ (current balance of Benjamin)
=> a = 2000 - b = 800$ (current balance of Alex)
Hope this helps!

Hi!
<h3>So, we need to figure out what r equals. </h3>
r doesn't have to be a number. r has to equal a value. A value can be variables, or numbers, it doesn't matter.
<h3>The equation says r = t + m. Read the equation out loud. </h3>
<u>r equals t plus m. </u>
<h3>There's the value of r! </h3><h2>The answer is the problem: r = t + m</h2>
Hope this helps! :)
