Answer:
the amount of money Ian invested is P = £2,500
Step-by-step explanation:
The standard formula for compound interest is given as;

Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
n = number of times compounded yearly.
t = time of investment in years
For this case, Given that;
A = £2652.25
t = 2 years
n = 1 (semiannually)
r = 3% = 0.03
substituting the given values into equation 1;

P = £2,500
the amount of money Ian invested is P = £2,500
Answer:
see explanation
Step-by-step explanation:
The perimeter P is the sum of the 4 sides of the rectangle.
The opposite sides of the rectangle are congruent , then
P = 2x + 1 + 2x + 1 + x + x ← collect like terms
P = 6x + 2
Hello,
Let's x the number of dimes
175-x then number of nickels
A dime is $0.10 and a nickel is $0.05.
0.10*x+0.05*(175-x)=13.30
10x-5x=1330-5*175
5x=455
x=91 (dimes) and 175-91=84 nickels
