Question

The week, Carrie spent

Answer 1

Answer:

$20.00

Step-by-step explanation:

Let x be the money Carrie had at the start of the week.

Add/Subtract from this amount (x) for the events occurring during the week:

     x    Start

-3.50   1 book

+1.25   Sugardaddy income

-7.50   Batman movie

===============

The end of the week Carrie has $10.25

Put this into one equation:

x - 3.50 + 1.25 - 7.50 = 10.25

x = 10.25 + 3.50 - 1.25 + 7.50

x = $20.00
