The Tanners have received an $8000 gift from one of their parents to invest in their child’s college education. they estimate that they will need $20000 in 12 years to achieve their educational goals for their child. What interest rate compounded semiannually would the Tanners need to achieve this goal?

Answers

Answer:

3.4%

Step-by-step explanation:

For given problem:

P=8000

n=2*12=24 compounding perods

A=12000

A/P=(1+i)^24

12000/8000=(1+i)^24

1.5=(1+i)^24

take log of both sides

log1.5=24log(1+i)

log1.5/24=log(1+i)

.007337=log(1+i)

10^(.007337)=1+i

1+i=1.017

i=1.017-1=.017 (interest rate per compounding period)

annual interest rate=2*.017=.034 or 3.4%

1. A school store sells pencils and erasers before school opens each day. On Monday, 13 pencils and

10 erasers were sold for $16.75. On Tuesday, 25 pencils and 2 erasen were sold for $19.85. What

is the price of a pencil? What is the price of an eraser.

Answers

Answer:

price of pencil is 0.74 and eraser is 0.72$

Step-by-step explanation:

Let, "p" represent pencils

and "e" represents erasers.

hence, according to question

13p+10e=16.75 ________(1)

and 25p+2e=19.85________(2)

Multiplying equation (2) by 5,

hence, 125p+10e=99.25________(3)

Substracting equation (3) and (1)

125p+10e-(13p+10e)=99.25-16.75

hence, 112p=82.5

p=0.74

substituting the value in equation (1),

13(0.74)+10e=16.75

9.57+10e=16.75

on solving,

e=0.72

hence, price of one pencil is 0.75$, and price of one eraser is $0.72
