For a school fundraising project, aiden and jacob collected money in the ratio 3.5: 6.8 jacob collected $115.50 more than aiden find the total amount of money collected

So when Aiden collects $3.50, Jacob collects $6.80

the difference between them is $3.30
and we have to make this number $115.50

$115.50 / $3.30 = 35
Why did we do this? Because now we know this:
$3.30 x 35 = $115.50
(that we have to multiply by 35)

So, now we just apply that onto the ratio
3.5 : 6.8
3.5 x 35 : 6.8 x 35
122.5 : 238

When Aiden collected $122.5, Jacob collected exactly $115.50 more than him.

Since we have to find the total amount, let's add them together!
$122.5 + $238 = $360.5

The answer is $360.5
