In a two-digit number the tens’ digit is 1 more than the units’ digit. the number itself is 6 times the sum of the digits. find the number.

54

Step-by-step explanation:

the number has to be divisable by 6 and 9*6= 54 also 5 is one more digit than 4

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
