PLEASE HELP, REWARD OF 100 POINTS! thanks :3

The total saving of Alex and Benjamin was 2000 U$D. Alex and Benjamin each donated [tex]\frac{1}{4}[\tex] and [tex]\frac{1}{5}[\tex] of their savings to an old folks home. The total amount donated by them was 440 U$D. What are the balances of Alex's and Benjamin's savings now?

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!

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
