Answer:
320 messages
Step-by-step explanation:
20 messages per dollar,
20 x 16 equals 320
The answer is 56m^2.
The formula for finding area of a triangle is A=b•h/2.
So the base is 16m and the height is 7m. 16m•7m=112m^2
Now divide 112m^2 by 2.
112m^2/2=56m^2
The total interest cost to Bette is $145.89
What is exact interest basis?
Exact interest means that the interest is computed on 365-day per year basis rather than a 360-day per year basis, which is the case with financial institutions.
The first task in this case is to determine the number of days from May 19, when the amount was borrowed till October 8, when loan repayment was effected.
There are 142 days between the two dates, hence, we can compute exact interest on the loan as shown by the below formula:
exact interest=loan principal*number of days the borrowing last/365days *interest rate
loan principal=$3000
number of days the borrowing last=142
interest rate=12.5%(1/2%=0.5%)
Exact interest=$3000*142/365*12.5%
Exact interest=$145.89
The amount would have been different if ordinary interest where the number of days in a year is deemed to be 360, was used instead

Increasing by 30% results in multiplication by 130/100, or 13/10. Setting the original amount of students to x, we write the equation:
13x/10=182
We multiply by 10 for a result of:
13x=1820
Dividing by 13, we have:
x=140
Thus, 140 students were in the club last year.
So,
10% is also known as one-tenth.
If 5 is one-tenth of something, that means that we can multiply 5 by 10 to get ten-tenths of that something.
5 * 10 = 50
The number is 50.
