Question

The expression 7h + 1.50d can be used to find the total earnings after h hours and d deliveries have been made.  Sally make after working 10 hours and making 3 deliveries total is ?

  1. $74.50
  2. $36
  3. $30
  4. $70

hintHint:

Substitute h with the value 10 and d with the value 3

The correct answer is: $74.50


    The expression 7h + 1.50d
    Substitute h= 10, d = 3
    =7(10) +1.50(3)
    =70+ 4.50
    =$74.50

    Use the distributive property to simplify the expression below:
    −2(6n+3)

    Given Expression:
    −2(6n+3)
    Distributive law states that every attribute inside the parenthesis can have same access of the attributes present outside the parenthesis.
    Example: a(b+ c) yields ab + ac.
    Hence, By applying Distributive Law to −2(6n+3) :
    −2(6n+3)
    =left parenthesis negative 2 cross times 6 n right parenthesis space plus space left parenthesis negative 2 cross times 3 right parenthesis
    =(-12n) + (-6)
    = -12n - 6.
    Hence, from distributive law −2(6n+3) yields -12n - 6.
