Answer:
After 6 month she can save enough money to buy the laptop.
Step-by-step explanation:
Consider the provided information.
Kendall is planning to buy a laptop for $1,200 each months she double the amount she saved the previous month if she saves $20 the first month.
Let say first month she save $20 then in next month she will save $40 and so on.
Let us make a table as shown below:
Months      Money Saved      Total Money Saved Â
1st            $20                 $20
2nd           $40            $40+$20 = $60
3rd           $80            $80+$60 = $140
4th           $160            $160+$140 = $300
5th           $320           $320+$300 = $620
6th           $640           $640+$620 = $1280
Hence, after 6 month she can save enough money to buy the laptop.
