Question
how do you write an expression for total salary for h hours of work if he is paid 8.25 per hour?
how do you write the correct translation for the quotient of 76.2 divided by an x?
how do you write an expression for the difference between 7.4 and a number x?

Answer
Hello Tatiana,

For part 1:
The total salary (S) is given by the product of "salary rate" (R) and the "duration of that work" (T).
Here, salary rate R=8.25 [dollars/hour], duration T=h[hour].

The required expression is S=R*T, or S=8.25h.

For part 2:
Consider dividing 29 by 3. We get 29=3*9+2
Understand what the following terms mean.

"Dividend" is the number being divided (29 in this example)
"Divisor" is the number doing the dividing (3 here)
"Quotient" is the number of times the divisor goes into the dividend (9 here, because 9*3=27)
"Remainder" is 3 in this example.

Accordingly, the quotient is <76.2/x>, where <a> means round the number "a" down to the nearest integer.

For part 3:
7.4-x
