Q. 1. Alice and Candice went shopping with the same amount of money at first. After Alice spent $480 and Candice spent $620, Alice had twice as much money as Candice. How much money did they have altogether at first?
Set Initial Amounts: Let's call the amount of money Alice and Candice each had at first x. After spending, Alice has x−$480 and Candice has x−$620. We're told Alice has twice as much as Candice after spending, so we can write the equation: x−$480=2(x−$620).
Distribute 2: Now, let's solve for x. First, distribute the 2 on the right side of the equation: x−$480=2x−$1240.
Move Terms: Next, we'll move all the x terms to one side and the numbers to the other side. So, subtract x from both sides to get: −$480=x−$1240.
