Answer:
$37.50
Step-by-step explanation:
Let beginning amount of money be
"s" for Sorin
and
"j" for Joel
The ratio is 4:7, so we can write:
Also,
After sorin GOT 50 MORE, the ratio became 8:7, so we can write:
Let's cross multiply 1st equation and find an expression for "j":
Now, we put this into 2nd and solve for s:
Cross multiply and solve for s:
So, "j" would be:
Sorin's allowance is $50
Joel's allowance is $87.50
Joel had 87.50 - 50 = $37.50 more than Sorin
