Mr. Herman has only $42.50 to spend at a clothing store. He wants to buy a shirt that costs $32, including tax, and some bracelets that cost $4.25 each, including tax. Which equation can be used to to determine x, the maximum number of bracelets Mr. Herman could buy.

42.50 = 32 + 4.25x

Step-by-step explanation:

Total amount with Herman = $42.50

Cost of shirt = $32

Cost of bracelets = $4.25 each

Which equation can be used to to determine x, the maximum number of bracelets Mr. Herman could buy.

Let

x = number of bracelets Herman could buy

Total amount = cost of shirt + cost of bracelets

42.50 = 32 + 4.25x

42.50 - 32 = 4.25x

10.50 = 4.25x

x = 10.50/4.25

x = 2.47

Approximately x = 2.5

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
