So he spent 1600 so x will represent original savings so
x-1600
then he spent 2/5 of the remainder on a refrigerator so
[(x-1600)2]/5
he had 1/3 of original savings left
[(x-1600)2]/5=1/3x
distrubute
(2x-3200)/5=1/3x
multiply both sides by 15
3(2x-3200)=5x
distrubute
6x-9600=5x
subtract 5x from both sides
x-9600=0
add 9600 to both sides
x=9600
3/8 + 3/8 = 6/8 The grandson will receive 2/8 or 25% of the 150k
so .25 * 150,000 = $37,500
1 ton is 2,000 lbs
9 x 2,000 = 18,000
So, 18,000 is equal to 9 tons.
Hope this helps. :)
