Sarah's money. They have $225 altogether

How much does Delia have?

- MATH -
**Reiny**, Monday, January 6, 2014 at 8:35pmDelia's money --- d

Sarah's money --- s

d+s = 225

(7/10)d = (1/5)s

7d/10 = s/5

35d = 10s

d = 10s/35

sub into d+s = 225

10s/35 + s = 225

times 35

10s + 35s = 7875

s = 175

then d = 225-175 = 50

Deliah has $50 and Sarah has $175

check: (7/1)(50) = 35

(1/5) of 175 = 35

yeahhh!
