Answer: The price of one CD would be $9.68.

Step-by-step explanation:

You take the total number and subtract the $12 because this is added after you begin to pay. Then you take that number which would be 145.2 and divide it by 15 and you will get 9.68.

1,030 at 4% compounded semiannually for 2 years
kotegsom [21]

Answer: $1114.91

Step-by-step explanation:

The formula for compound interest is

A= P(1+\frac{r}{n})^{nt}  \\

Where

A = final amount

P = initial principal balance (1030 for this)

r = interest rate (0.04 for this)

n = number of times interest applied per time period (2 for this)

t = number of time periods elapsed (2 for this)

A= 1030(1+\frac{.04}{2})^{(2)(2)}  \\\\A= 1030(1+0.02)^{4} \\A=1030(1.02)^4\\A=1114.905125

This rounds up to $1114.91

Umm it’s to question just label it a and b
xxMikexx [17]

A) Scale of map is 1: 30,000

This is assuming that it meant 1 centimetre = 30,000 metres, for it gives no other information.

Multiply 1 with 30,000: 30,000 x `1 = 30,000

30,000 metres is your answer.

B) Scale is 1 inch: 6 miles. You are given 2.5 inches.

Remember that 1 inch = 6 miles.

Multiply 2.5 to both sides: (2.5) * 1 inch = (2.5) * 6 miles

2.5 inch = 2.5 * 6 miles

2.5 inch = 15 miles

15 miles is your answer.
