Answer:
It would take 10 years for the given sum of money be doubled at the given simple interest rate.
Step-by-step explanation:
A 10% interest would be added to the the principal amount after each year. So the interest would reach 100% i.e. equal to the principal amount in 10 years.
The equation would be 60h=m
The first one. Substitute both $82 and $42 to get the 4 and 9 hundreds.
Y = -1/8*82+57/4 = 4 hundreds
Answer: interest = $ 3,629.34
Step-by-step explanation:
Complete question
(Marlie will be starting college next year, federal unsubsidized student loan in the amount of $18,800 at 4.29%. She knows that during this non-payment time, interest will accrue at 4.29%. Suppose Marlie only paid the interest during her four years in school and the six-month grace period. What will she now pay in interest over the term of the loan.)
This question relates to interest over a single period of time and since it's not compounded, we use formula for simple interest to calculate the interest accrued.
Data;
P = $18,800
R = 4.29% = 0.0429
T = 4.5 years
S.I = ?
S.I = PRT
S.I = 18,800 * 0.0429 * 4.5
S.I = $3,629.34
Therefore she'll need to pay $3,629.34 as interest accrued.
Answer: 134,061.9 dollar and 118,222.45 lb
To answer this question you need to convert each unit.
First, 1 dollar equal to 100 pennies. That mean the equation would be: <span>13,406,190 pennies x 1 dollar/100 pennies = 134,061.9 dollar
Each penny weight 4 grams and 1 lb equal to </span>453.592grams. Then the equation would be:
13,406,190 pennies x 4 grams/pennies x 1lb/453.592 grams= 118,222.45 lb
