Answer:
6 ft longer (total length of 15ft)
Step-by-step explanation:
the initial dimensions are:
length: 
width: 
the area area of the garden is given by:

so the original area is:

, and we can only change the length, the width will still be 8ft.

Answer:
6 laptops.
Step-by-step explanation:
$6500 is the budget. If each textbook costs $116, and 30 textbooks are needed, you multiply.
116 x 30 = 3480.
3480 was spent on the textbooks, and the rest needs to go into laptops.
6500 - 3480 = 3020.
Now to find out how many laptops can be bought with the remaining money, divide.
3020 / 439 = 6.88 (You can't buy a portion of a laptop, so you have to take the biggest whole number, which is 6).
