Answer:
$3100
Step-by-step explanation:
Step one:
given data
Principal = $2500
rate = 1.2%
time = 20 years
Step two:
The simple interest is expressed as
SI= PRT/100
substitute
SI= 2500*1.2*20/100
SI= $600
The account balance after 20 years is
= principal + Simple interest
= 2500+600
= $3100
Answer:
D. 5y^2
Step-by-step explanation:
2x + 3y^2 - 2(x - y^2)
2 * x = 2x
2 * -y^2 = -2y^2
2x + 3y^2 - 2x + 2y^2
Combine like terms
2x and -2x cancel ach other out
3y^2 + 2y^2 = 5y^2
D. 5y^2
Answer:
A
Step-by-step explanation:
subtraction and addition comes first and multiplication and division comes after.
The right answer is Option B.
Step-by-step explanation:
Let,
Number of songs = x
Price of 1 song = $0.99
Membership fee = $19.99
Total amount paid = $21.97
According to given statement;
0.99x+19.99=21.97
Subtracting 19.99 from both sides
Dividing both sides by 0.99
Lauren bought 2 songs.
The right answer is Option B.
