Answer:

Step-by-step explanation:

C(n) = 5n, 0 ≤ n ≤ 10 You would use this equation for finding the cost of 10 shirts. Since 10 is equal to 10.

C(n) = 5n, 0 ≤ n ≤ 10 ← You can ignore the 0 ≤n ≤10 part.

C(10) = 5(10) Input the value 10 as x.

C(10) = 50 Simplified

Next,

C(n) = 4n + 5, n > 10 You would use this equation for finding the cost of 12shirts. Since 12 is greater than 10.

C(n) = 4n + 5, n > 10 ← You can ignore the n>10 part.

C(12) = 4(12) + 5, n > 10 Input the value of 12 as x.

C(12) = 48 + 5 Simplify

C(12) = 53

Finally,

The question is asking you to find the difference between the cost of 12 shirts and the cost of 10 shirts. So the formula would be C(12) - C(10).

C(12) - C(10)

(53) - (50) Input the values of C(12) and C(10).

= 3 Simplify.

The answer is 3.

Find the interest rate needed for the sinking fund to reach the required amount. Assume that the compounding period is the same

Maslowich

Answer:

so rate is 4.72 %

Step-by-step explanation:

Given data

time (t) = 5 year = 5×4 = 20 quarterly

amount = $27456

principal = $1225

to find out

interest rate (r)

solution

we use here amount formula that is

amount = principal ( $(1+r)^{t}$ -1 ) / r .....................1

put all value principal , amount and time in equation 1 and we get rate

rate is r/4 because it is quarterly payment

amount = principal ( $(1+r/4)^{t}$ -1 ) / r/4

27456 = 1225 ( $(1+r/4)^{20}$ -1 ) / r/4

( $(1+r/4)^{20}$ -1 ) / r/4 = 27456/ 1225

( $(1+r)^{20}$ -1 ) / r = 27456/ (1225 × 4)

( $(1+r)^{20}$ -1 ) = r 27456/ (1225 × 4)

now by the tvm solver and amount $27456

graph value

we get r = 0.0472

so rate is 4.72 %

Tyler's mom purchased a savings bond for Tyler. The value of the savings bond increases by 4% each year. One year after it was p

Gemiola [76]

Answer:

The value of the bond when Tyler's mom purchased it was $150

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

$f(x)=a(b)^{x}$

where

a is the initial value (y-intercept)

b is the base

r is the rate

b=(1+r)

In this problem

r=4%=4/100=0.04

b=1+0.04=1.04

substitute

$f(x)=a(1.04)^{x}$

where

x is the number of years since the savings bond was purchased

f(x) is the value of the savings bond

For x=1

f(x)=$156

substitute

$156=a(1.04)^{1}$

Solve for a

$156=a(1.04)$

$a=\$150$

therefore

The value of the bond when Tyler's mom purchased it was $150

eimsori [14]

$\frac{231}{4}$ ✅

Step-by-step explanation:

$\frac{33}{4} \times \frac{21}{3} \\ = \frac{11 \times 21}{4} \\ = \frac{231}{4}$

Note:-

A fraction is said to be written in its lowest form if its numerator and denominator are prime, that is, they have no common factors other than 1.

Leon has already run 1 mile on his own, and he expects to run 3 miles during each track practice. Write an equation that shows t

maks197457 [2]

Answer:

d = 1 + 3p

Step-by-step explanation:

Leon already ran 1 miles on his own and he is expected to cover a distance d of 3 miles during each practice. The number of practices is expressed as p and the distance covered is expressed as d.

For every track practice he is expected to cover a distance of 3 miles. Recall he has already cover 1 mile on his own.

Therefore, the relationship between the practices p and the distance d can be expressed as follows.

number of track practice = p

distance covered = d

The distance covered d in miles is 1 miles plus the number of track practice p multiply by 3

d = 1 + 3p
