645 m 86 cm
Answer:
$300
Step-by-step explanation:
Let Dave's saving be D and Sam's savings be S
- <u>"At first, the ratio of Dave's savings to Sam's savings was 5:4":</u>
- <u>"After each of them donated $40 to charity, the ratio of Dave's savings to Sam's savings became 13:10":</u>
<em>So we subtract 40 from each of them and then the ratio becomes 13 is to 10. Hence we can write:</em>
<em>Plugging in into S (as we found earlier), we can solve for D (our answer):</em>
So, Dave's savings at first, D, is $300.
