For her gift present, Lisa has saved $1200. She asks her mother, as well as her brother, to help her raise the total amount of money she needs to buy the gift.,If her mother gave her 3/5 times of what she had saved and her brother gave her twice the amount her mother gave her, calculate the price of the gift she wanted to buy if she still had $400 less. Let's be accurate as possible.
Lisa's mother gave her 3 / 5 * $1200 = $720 for her birthday gift. She also received 2 * $720 = $1440 from her brother for the gift. If she still had to find $400 to fully reach her birthday gift cost, it means her gift's total cost was $1200 + $1440 + $720 + $400 = $3760.
The answer: 3760.
