Step-by-step explanation:
increase = 120 - 80 = 40 which is 50 % of 80
The amount of money Elena has to give Priya so she has 3 times Elena's balance is $12
<u>Given the Parameters</u> :
- Amount Elena has = $84
- Amount Priya has = $12
- Let the amount Elena gives out to Priya = p
<u>We can set up an expression thus</u> :
84 - p = 3(p + 12)
84 - p = 3p + 36
Collect like terms :
-p - 3p = 36 - 84
-4p = - 48
p = 48 / 4
p = 12
Therefore, Elena has to give $12 to Priya, so that Priya has 3 times the amount owned by Elena.
