Everyone bought a $6 souvenir so 6x7= $42
Then subtract that from $147. 147-42=105.
They spent $105 on 7 tickets so then divide 105 by 7. 105/7=15. Each ticket costed $15
He starts saving $ in January to buy a gift in June. (which is 6 months, or 5 months not including June)
Each month he saves 2/3 of his allowance, which is $14.
[his allowance each month is $21, 2/3 of his allowance is $14]
(you multiply 21 by 2/3 = 42/3 = 14)
The gift he wants to buy is $110
x = the number of months
y = total cost
14x = y
14x = 110 [he saves $14 each month, he wants to have a total of $110 to buy a gift]
Plug in 6 for x in the equation
14(6) = 110
84 = 110 (He is $26 short, so saving either for 5 or 6 months will not get Ian $110)
Ian will not have enough money because he is $26 short for 6 months or $40 short for 5 months. (you can decide whether you want to go by 5 months or 6(including June), sorry for the confusing answer)
Cool question (Although it is tough somewhat)
1st step is to visualize the change from C to C'
we have C'(8,-3) and C(3,-8) supposedly for C because it doesn't show any real values.. Nonetheless
from C to C' there has been a rotation of 90 degrees clockwise
proof:
Clockwise 90 degrees rotation law : (x,y) --> (y,-x) and it proves the change from C to C'
Therefor
all left to do is estimate the B point coordinates and implement the law of rotation
B(8,-7) Now implement a rotation of 90 degrees clockwise
we would get
B'(7,-8)
Hope that helps
