The interest rate is B. 4%
Given:
Principal = 450
Interest = 126
term = 7
rate = ?
Simple Interest is computed by multiplying the Principal, rate, and term.
Interest = P × r × t
126 = 450 × r × 7
126 = 3150r
r = 126/3150
r = 0.04 x 100% = 4%
To check:
I = 450 × 0.04 x 7
I = 18 × 7
I = 126

Answer: The size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.
Step-by-step explanation:
Let the original size of computer be 100x , then if it increases by 20 %
then the new size of the computer=100x +20% of 100x

The size of computer after 20% increase= 120x
If size of computer is decreased by 20 % then
The new size of computer= 120x - 20% of 120 x

On comparing it to the original size , we get

Thus, the size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.

Answer:
Total number of cards = 32(4) or y=32(4)
Roberto had 128 cards.
Step-by-step explanation:
Consider the provided information.
Part (A)
He gave his four friends 32 baseball cards each.
Let the number of cards he have before giving them to his friends is y.
This can be written as:
y = 32(4)
Part (B)
Now solve the above equation as shown.
y = 32(4)
Multiply 32 with 4
y = 128
Hence, Roberto had 128 cards.
