Answer:
The principal amont was $35,000
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this problem, we have that:
We want to find P. So
The principal amont was $35,000
it should be 125/5 is 25
so now we know each 1/5 os 25
in order to find 35 we multiply 25 by 3
25 x 3 is 75
75 students HAVE a mobile phone
now subtract 125-75 and you should get 50
final answer is 50
Answer:
the cost of each notebook is $4.8
Step-by-step explanation:
Cost of each notebook= ?
Cost of a poster = $6
Total amount she spent = $20.40
If we subtract the cost of poster from total amount we get the cost of 3 notebooks.
$20.40-$6
=$ 14.4
It means the cost of 3 notebooks = $14.4
To find the cost of each notebook divide the cost of 3 notebooks by the number of books.
=14.4/3
=$4.8
Thus the cost of each notebook is $4.8....
Answer:
12.565 + 8 + 10 + 10 = 40.565
Find the circumfrence of the circle and divide that by 2. Then add the other sides.
The inequality that models this situation is:
<u>Solving the inequality</u>, it is found that 5 is the least number of buses needed to transport the Math Team.
Since in each bus <u>holds eight people</u>, with n buses, the total number of people is given by:
There are 35 students, and two faculty advisors going on the trip, hence, the inequality is:
To solve the inequality, we treat it similarly to an equality, thus:
There has to be a whole number of buses, thus 5 is the least number of buses needed to transport the Math Team.
