The answer is b because it has the 3 with 6 corresponding.<span />
20% of $20 is 4. So $4 divided by two people is $2.
$2 is your answer.
Let's split these two situations up.
Linda
Linda deposits $1,800 into an account that pays 7.5% interest, compounded.
The equation:
1,800× 1.075^x=y
Let's put in 10 for x.
1.075^10= 2.06103156 × 1,800= 3,709.85681≈ 3,710
Anna
Anna deposits $4,000 into an account that pays 5% interest, compounded.
The equation:
4,000× 1.05^x=y
Let's put in 10 for x.
1.05×10= 1.62889463×4,000= 6515.57852= 6516
A) Linda's account: $3,710
Anna's account: $6,516
<AEB and <DEC are equal so:
5x-10=3x+40
5x-3x=40+10
2x=50
x=25
<AEB= 5x-10
<AEB= 5*25-10
<AEB=115
