Hi there!

Your answer is:

A) Barbara didn't consider the number of water bottles!

Step-by-step explanation:

1.49(tea) + 1.25(water) = 100 (CORRECT EQUATION)

1.49(tea) + 1.25 = 100 (BARBARAS WRONG EQUATION)

She forgot to add the variable for water!

Hope this helps

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.
