Money left = 180.55
Answer:
(- 1, 8 )
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
(8, - 1 ) → (- 1, 8 )
So 5.10 is 100% and 0.57 is x%
percent means parts out of 100
5.10/100%=0.57/x% since they are equal (exg 2/4=3/6)
5.10/100=0.57/x
multipy both sides by x/0.57 to clear fraciton
(5.1x)/57=1
multiply both sides by 57 to get rid of the denomeator (bottom number
5.1x=57
divde both sides by 5.1
x=11.1765
increase of 11.2%
( an easy way is (0.57/5.1) times 100)
Let jae have x dollars. Thus, we can make the equation:-
x + 3x + 2*(3x) = 400
4x + 6x = 400
10x = 400
x = 40
So jae has $40 and
jaspar has 3x = 3* 40
= $120 dollars (answer
