Simple interest is based on the principal amount of a loan or deposit. ... Simple interest is calculated only on the principal amount of a loan or deposit, so it is easier to determine than compound interest.
Let us assume rent for a child = $x per hour and
Rent for an adult = $ y per hour.
We are given number of children = 3.
Number of adults = 1.
Rent for 3 children at the rate $x per hour = 3*x = 3x.
Rent for 1 adult at the rate $y per hour = 1*y = y.
We are given number of hours of rafting trip = h hours.
Total cost of 3 children and 1 adult for h hours =h times (Cost of 3 children and 1 adult for each hour).
= h*(3x+y).
Therefore, h(3x+y) is the final expression for the total cost of h hours of rafting trip.
If you are given values of x, y or h, you can plug those values in this expression.
In the addition problem attached, the letters H = 2, E = 3, A = 9. See the explanation below.
<h3>What is the explanation for the above?</h3>
In the problem, A depicts a single digit i.e; A < 9.
=> 4H<10
=>H<3
i.e; H should be 1 or 2.
In units column, 4E should have H in units place in the result. i.e; 1 or 2
As 4E is always an even number, H cannot be 1.
=> H = 2
If H = 2, E can be 3 or 8 for 4E to end in 2.
If E = 8, the result will be a three-digit number => E = 3
So if H = 2 and E = 3
A = 9
Therefore, the letters
H = 2,
E = 3, and
A = 9.
