2.no, she should have set it up x/45 = 100/45

3.no, she should have set it up 45/x =75/100

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.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
