They would have to pay $157.50 due to interest in addition to the $1,400.
Explanation:
The initial borrowed amount was $1,400. This bank has an interest rate of 7.5% every year. This means that for every year that money is kept in this account, they must pay the bank 7.5%. To do this we must calculate how much 7.5% of $1,400 is.
7.5% of $1,400 is 0.075 * $1,400 =$105
So for every year, the interest of $105 must be paid to the bank. To calculate total interest we multiply this interest amount and the number of years.
So after 18 months (1.5 years)= $105 * 1.5 years = $157.5.
So interest gained in 18 months is $157.5 but this is only the interest amount. We must add the initial amount with this to find the total amount to be paid to the bank.
Total amount to be paid= Inital amount + Amount due to interest= $1,400 + $157.5= $1,557.50.
<u>Answer</u>
C. 4 + 6
D. 3.15151515.. + 4.6
E. √64 × √25
<u>Explanation</u>
A rational number is a number that can be expressed as a quotient or a fraction. That is it can be written as a/b.
π×6 = 6π ⇒ can not be written as a rational number.
√3 + √5 ⇒ the sum of two irrational numbers can not be rational.
4 + 6 = 10. Ten is a rational number. it can be written as 10/1
3.15151515.. + 4.6 = 104/33 + 23/5
= 1279/165
√64 × √25 = 8×5=40 This can be written as 40/1
