The correct answer is 2 so Grace was the correct student
Nick.
40 - 1.50
38.5 - 1.50
37 - 1.50
35.5 - 1.50
34 - 1.50
32.5 - 1.50
31 - 1.50
29.5 - 1.50
27 - 1.50
25.5 - 1.50
= 24. 10 days.
24 - 1.50
= 22.5 after 11 days.
Bob:
9 + 1.50
10.50 + 1.50
12 + 1.50
13.50 + 1.50
15 + 1.50
16.50 + 1.50
18 + 1.50
19.50 + 1.50
21 + 1.50
22.50 + 1.50
Same amount of money: 24. After 10 days.
25.50 + 1.50
Bob will have more money then Nick in 11 days. He'll have 27 dollars when Nick has 22.5 dollars.
Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
