Answer:
the answer is 180 dollars
Step-by-step explanation:
20 is 10% of 200 so just subtract that
<span> x+2a=4x
2a = 3x
a = 3x/2
a =1.5x</span>
First make the denominator equal for both fractions.
The LCM of 8 and 5 is 40, so 40 will be the common denominator.
3/8=15/40 and 2/5=16/40
Add them together.
15/40+16/40=31/40
He has 9/40 of his money left, which means 9/40 of the total money=$6.72
Make an equation to solve for how much money he had when he started (x).
6.72/x=9/40
After solving, x= about $29.87
