Answer:
Large books = 11
Small books = 6
Step-by-step explanation:
7x + 5y = 107
7x = 107 - 5y
x = 107/7 - 5y/7
5x + 7y = 97
5 (107/7 - 5y/7) + 7y = 97
535/7 - 25y/7 + 7y = 97
535/7 + 24y/7 = 97
535 + 24y = 679
24y = 679 - 535
y = 144/24 = 6: So x =
7x + 5(6) = 107
7x = 107-30
x = 77-7 = 11

Step-by-step explanation:
You want to calculate the interest on $550 at 2.1% interest per year after 4 years.
The formula we'll use for this is the simple interest formula, or:
I = P x r x t
P is the principal amount, $550.00.
r is the interest rate, 2.1% per year, or in decimal form, 2.1/100=0.021.
t is the time involved, 4 years.
So, t is 4 year time periods.
To find the simple interest, we multiply 550 × 0.021 × 4 to get that:
The interest is: $46.20
